David S. Rodriguez:

Both characters should be colored black instead of blue against the empty white negative space. The characters are already well developed and I think their personalities could be fleshed out more by having a visual setting instead of an empty space. Still, it is decent and I see the effort put into it.

Richard Clark:

Not bad. When the character on the right says, "not right off hand", his motion where his whole body turns towards the other character is a bit strange... it's too much. I'd say next time shoot reference of yourself doing the motion. FYI... that is one long nose.
