Thanks in advanced for any feedback!

I definitely made some mistakes on the form intersections and the dissections could have gone better, but I feel like I learned a lot from going through these exercises.

Hi Cornball, Congratulations on finishing lesson 2. I'll be giving you feedback, pointing out mistakes you've made as well as thing you did good.

Organic arrows

  • Your linework looks mostly fine. Some of the longer lines you've drawn in multiple parts. Try to place them as one continuous line. This may be difficult because of how long these lines get but you'll get better at it with practice.

  • The increased linethickness is very scratchy with multiple small lines. These should also be just one additional line, placed using the ghosting method.

  • The arrows get smaller towards the back properly.

Organic intersections

  • The sausage shapes have a consistent thickness.

  • The ellipses are drawn properly going through each one 2-3 times.

  • The contours don't have varying degrees as described in this picture. Some of them also have a flat section in the middle. When drawing these use the ghosting method as if you were drawing an ellipse but only put you pen down for the front part.

Texture analysis

  • There is a nice gradient from light to dark in the textures.

  • The black bar on the left blends a bit with the texture but it is still noticeable just like the white bar on the right. See this picture for reference.


  • Your textures wrap around the sausage shape nicely. Most of them also get darker towards the edges.

  • You've mostly drawn cast shades. However for some of the textures you've drawn contours like the watermelon and sunflower textures.

Form intersections

  • Your linework on the base shapes looks good. The hatching lines are a bit arched sometimes which is often a result of rushing these. Take your time when hatching and use the ghosting method and you'll be fine. For the added lineweight the same applies as I said in the organic arrows exercise.

  • I don't see major mistakes in the intersections. You look like you have a good understanding in how shapes interact in 3D space.

Organic intersections

  • Both pages look like they are solid piles of sausage shapes.

  • The shadows wrap nicely around the shapes.

  • Same as before applies to the lineweight.

Overall very nice work. You are ready to continue with lesson 3.

Next Steps:

  • Continue with lesson 3

Thanks for the feedback Fable! All very valid criticisms - I definitely do tend to add line weight in segments on curved lines because whenever I try in a single line it always ends up diverging and looking like a separate line rather than line weight, even with ghosting. That's not a justification, just my reasoning - I understand that this is a bad practice and that I should try adding weight to curves in single strokes, even if they end up looking like separate lines (these are exercises, not finished drawings).

I didn't even think to vary the degrees of my contour curves - I did for the ellipses but for some reason thew that away for curves! Thanks for pointing this out - I did ghost through the entire ellipses for the curves, but failed to vary the degrees properly. I will pay attention to this in the future.

My gradients definitely leave something to be desired - I hope to improve on blending them more with the 25 texture challenge. Some of the textures for the dissections I found difficult to draw with purely cast shadows, but I probably should have just picked a different texture then.

Overall very helpful feedback - thanks again!

Mistakes in the textures are not really a problem. As stated in the lesson, this is the first time practicing textures which is a very difficult subject and mistakes are very common. It's commendable that you try difficult textures and you should continue doing so. Just be aware of the possible mistakes and when you finish a texture look back at it critically and if you spot a mistake, like drawing contours, think to yourself what you could improve next time.

The recommendation below is an advertisement. Most of the links here are part of Amazon's affiliate program (unless otherwise stated), which helps support this website. It's also more than that - it's a hand-picked recommendation of something I've used myself. If you're interested, here is a full list.


This is another one of those things that aren't sold through Amazon, so I don't get a commission on it - but it's just too good to leave out. PureRef is a fantastic piece of software that is both Windows and Mac compatible. It's used for collecting reference and compiling them into a moodboard. You can move them around freely, have them automatically arranged, zoom in/out and even scale/flip/rotate images as you please. If needed, you can also add little text notes.

When starting on a project, I'll often open it up and start dragging reference images off the internet onto the board. When I'm done, I'll save out a '.pur' file, which embeds all the images. They can get pretty big, but are way more convenient than hauling around folders full of separate images.

Did I mention you can get it for free? The developer allows you to pay whatever amount you want for it. They recommend $5, but they'll allow you to take it for nothing. Really though, with software this versatile and polished, you really should throw them a few bucks if you pick it up. It's more than worth it.
