I sketched a picture of Iron Man last week. Iron Man has always been really fun to draw for me because his suit is so detailed. (Although the pictures below are only of his shoulders and head) So I drew Iron Man, but I really wasn't too happy with how it turned out. So I remade it, and decided to post both of them here.
This one took me twenty minutes.
The one below took me about an hour.
Here is another picture of the same one. (Down below)
And both sketches together.
Although, I think the camera focused a little more on the one done in the sketchbook.
