Nice.
Pretty cool overall, especially the character and pose, but I think you should utilize the layer feature on Corel. It eliminates all of those messy little pixel spots on the lines, and makes the drawing look way more professional. By using layers like I mentioned, you can draw the lines on a separate later, then colour on an overlying or underlying layer, totally un-affecting your lines. :) That, or you could just make a new layer over a pencil sketch (if you scanned it) and set the new blank layer to 'multiply.' Thay way, the color just goes right overtop and acts as if the pencil lines are semi-transparent.
You've obviously got a great drawing capability, so it's a shame that little pixels would distract from that.
Keep up the good work!
Just some humble constructive criticizm. c:
