Hi there! This is really nice! I applaud your commitment to analyzing your work and taking notes! I also like how you take your time and think about each shape and what mood it could convey. I definitely need to do more of that as well. The only thing I would note is to also keep in mind your line quality. The buffalo seems to have some timid lines that are a bit wobbly. An idea would be to split more complex curves into shorter segments. This would allow you to draw each segment with more confidence. Also, and I might be wrong on this, but the digital brush you use seems to be some sort of... oil painting brush? Now, I’m not saying you need super special tools to create good art. I’m sure you could make this particular brush work as well. But in the beginning, you might want to play around with different brush options and see if you can find anything that resembles a graphite/colored pencil. Something that would allow you to draw more comfortably with speed and confidence. I hope this helps. And again, great job with the self-analysis!
