Nice

I am loving that you added some red in here almost feels like you could have added even more red like a frame or border, So nice design here on this sketch allthough no or little color I could see you adding some color to bring out the design more but overall this was just pretty well done work you have here, hope to see much more from you and great sketch you have here its a fantastic piece.

Nice contrast

I always liked this style. Very nice contrasting. Love black and white. The lines are a bit shaky, but that's all right. If its vector and the drawing is simple like this you might like to use the pen and curve tools sometimes to do an outline first. It would get rid of all that digital shakiness just mentioned. :)

awesome

I love this style, keep it up (:
