Hi! I'm Kotka and I'll be reviewing your work today. Congratulations on your clean, confident strokes and lines! You will have no problem going forward but there are some things that need to get a little more in order before youäre completely done. Let's jump into it!

Organic Arrows

You correctly show perspective by compressing the space between the curves farther away, and overlapping edges where it should. You have avoided the most serious mistakes, which is good. Your curves and lines look confident and are good. Likewise, I get a feeling that you are in a hurry - although too slow comes with its own problems such as wobbly lines (at this point, it's not an issue for you and I wouldn't worry about it). In your arrows, I see a lot of overstretched connection points - that is, the curve has gone a little too far, or maybe it was the line. Being too fast is probably a common reason for this. Try slowing down just a little and see whether this can be improved.

I would like you to try adding one or two careful passes of line weight where the topmost curve overlaps next time you do this exercise.

Organic Forms with Contour Lines

Your sausages are properly round at the edges, and easy to understand, but be wary of differently sized ends! In some sausages, one of your end tends to be a little smaller, which you should avoid. Furthermore, it looks like you're hurrying here too - your ellipses are mostly within the sausage and follow the center line, but they lack enough degree variation one would expect from perspective change. The overall impression is that they are floating a bit too arbitrarily inside the sausage, which is why I'll ask for a tiny revision. Slow down and try to be a bit more precise.

Your contour line sausages are better than the ellipse sausages - a lot less but in some of them, there is still too little degree variation along the sausage.

Texture analysis

You draw the cast shadows properly and avoid focusing on outlines. I can see the texture going dark to light. I would like to see deeper and darker cast shadows and less and lighter. In other words, more contrast between dark and light areas. For dark areas, you can try adding more blacks. For the light areas, try "lost edges" as explained in the lesson section. Keep this in mind and definitely keep doing this exercises as a warm-up.

Dissection

Well done! I can see you minding the curvature with more condensed shapes closer to the turns of the sausages, and you break the silhouette in the additive, proper way. If I'm to say anything, it's the same advice as for the Texture Analysis - try to push the darks darker, and the lights with more lost edges.

Form Intersections

This is a very hard exercise and the first times doing it, there will rarely be and "obvious" correct intersection line. You have managed to avoid the most common errors - your forms are mostly equilateral, you have grouped them correctly and there are no overpasses with wobbly lines. Keep doing this as warm-up, and try to tighten your ellipses (don't be too fast!) to avoid too many passes. Your drawings will look a lot neater. Ghost like in the previous lesson, and when youäre sure, put down the line. This will most probably fix your overshooting errors, which can also be seen in this exercise.

Organic Intersections

You have done everything correctly by using uncomplicated forms, stacked perpendicularly, and the cast shadows warp around the shape below in a believable way. What you suffered from in the Organic Forms with Contour Lines is also visible here. The drawing looks rushed and a bit messy. The contour lines seem to float around in some parts of the sausages. I will not ask for a revision because you got the cast shadow and stacking part correct here and also because your main issue will be addressed in another revision, but remember to keep this in mind and do a little more of these as a warm-up until it looks less busy.
