Please critique my work. I tried my best but I know it has flaws.

Thank you.

Organic Arrows

Your arrows are smooth & flowing through the space. You've also compressed & expanded them to show the depth, good wok. Your lineweight position is almost good, just make sure you're using them only for the overlapping part(where you did the hatching) to highlight the edge close to the viewer.


Other than few(especially the top left & bottom right), your leaves are following the flow line naturally. You can work on them a bit to make it look more natural. Use real leaves as reference if you can.

You've broken the silhouette in some of the leaves but in many of them you've cut back into already drawn part. It is recommended to do constructions using addtion & when you do add or remove stuff, think of whether it would be raised or lowered relatively.

One thing I would recommend is lowering the amount of contour lines drawl. Since we're not drawing exact copies of a reference, draw a contour for veins only if help convey the form more or doens't make the drawing more noisy.


Sometimes the ellipses here are not perpendicular to their minor axis(flow line of branch), see https://drawabox.com/lesson/1/5/minoraxis. Ghost multiple time before placing the mark for them as if not placed well they can break the drawing instantly.

The edges of these branches are straying a little but you've done them(along with forking) as instructed, these edges will get better with more practice.

Also you'll have easier time drawing these branches, if you place those ellipses near the extreme/sudden curves of flow line.

Plants Drawings

While you've done the required amount of pages, I think you repeated same plants(most of them are from demos) quite a lot. You could've used some variations.

Nice work on keeping the parts of plants enclosed within it's planned ellipse.

In some of the plants(like Pitcher plant) where you used branches, you've ignored the instruction of doing each edges separately, while it might seems easier that way it won't result in a smooth edge(since there are curves involved).

You've also broken the silhouette of the drawing to convey the forms of the plants.

You've drawn flow line for each petal & leaves and while some of them are stiff(like in flowers) & not natural(some in potato plants), you'll improve over time & with enough practice. Always spend good amount of time observing the flow in the reference before placing mark on the page.

While some mushroom are done well, I think some of them could use some stability, so they don't look as if they'll fall anytime, do minor axis for those construction before placing the ellipses.

In Cacti, I see that you've drawn the thorns all over the drawing. Don't do this, it can make drawing very noisy & hard to look at. When doing these details, you want to have a focal point, so viewer's eye can easily flow through the drawing, see the implicit detail section of lesson 2 https://drawabox.com/lesson/2/2/implicitexplicit.


Your plants construction are done as instructed. Please do those ellipses perpendicular to the minor or they would break the form you're constructing, do them in your warm ups & read the ellipses section from lesson 1 again if you can.

Congrats on completing lesson 3!

Next Steps:

Feel free to start lesson 4.

Thanks for your critique. I really needed this and now have a better understanding on what I need to improve on. As for repeating some of the plants, I thought you could only do the plants that Drawabox made lesson tutorials on. If you can stray on to other plants, that would be nice to know.

Thank you

It's actually recommended to do plant drawings(& insects/animals in future lessons) using references outside of the demos. Demos help you in understanding how you can think about constructions in differents stuffs(because even in plants, there are lots of variety). So feel free to use references from now on.

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.
