Thanks a lot for the feedback, I am very new to this so your critique is highly valued. What do you mean exactly with "banding"? I drew this in MS Paint if that offers any explanation? Thanks again :)

Interesting, nice detail for only two colors, kinda looks like a sketch. The thing that bothers me the most is then you have two lines right next to each other, like on the lip and out eyes. Not sure what your goal was, but I think it counts as banding which kinda causes problems in pixel arts.
