This was drawn from life, but i took a pic for you guys to compare. I tried to autistically measure proportion and angles but it still looks a but shit. I know it's not good in any way, but i feel my texture, details, and shading is especially bad. (Some of this might be because the light changed and I had to go before i really finished, but i still spent like an hour on this turd.)

I think some of it might be the small size of the paper (9"x6") and the fact that it's so smooth, but that might just me blaming my lack of skill on equipment.
