When did you start?
The recolor isn't bad for a beginner (the purple fox). Just make sure not to use pure default Paint colors (try altering them a little to start with, then after a while, develop your own) and save the images as png, not 24-bitmap (24-bitmap will convert to JPEG, or, at least give the image a JPEG-ish quality).
Keep posting up stuff! And also, make sure to keep the comics in the comic forum.
