OK this is a sample of how well I do when I have not done much in the way of drawing, and when I have not used a reference other than memory.
It looks crappy compared to other art I can do when I have a reference. xD

(I'm such a copy cat on my other art. I can draw what I see quite well. I'm trying to draw my own things and make reference art based of my own things I make, or anatomy things I can find... so far this is what I have without any kind of reference other than my crappy memory lol)
