I don't think they are half bad for a first try, really.
This one is just Bender smoking a cigar... I have a photocopy of it on my dorm room door with a dry erase speech bubble where I put something different every week or so.
This one I just drew today, I like the lineart but the coloring is not very good because of limited marker selection (hence why Bender is sort of purple.) Fry also looks awkward because I messed up inking his eyes, and I had to do his skin with colored pencil as I had no marker even remotely close to skin color.
I really have no idea what prompted me to draw that, but... yeah.
Any critiscm is welcome. I still have a great deal of trouble drawing Fry.
