Didn't know you were an artist on here as well. To be good at both is definitely a difficult feat to accomplish. So to that, I tip my hair pick to you, since my afro doesn't permit me to wear hats.
I skimmed through as much as I could, and from what I've seen so far you definitely got some good stuff. I could tell you were improving slightly with each drawing as time went on. I don't hang around the artist section like I used to, but I'll be sure to be on the lookout for your future drawings. Keep it up!
Side Note: Your most recent sketch reminds me of the fact that I have a habit drawing three dimensional cubes whenever I'm bored with a piece of paper in front of me. Don't know why, just something random I partake in.
