If you don't mind me asking.. Do you draw on paper and then colour the scanned drawing? How do you make your lines? And what graphics program do you use?
Your drawings are pretty good, and I'm sure you can get even better with practice.
The only thing that has kinda bothered me is the way the lines look so scratchy and jagged. From what I know about colouring, I assume you use a fill bucket to colour (or even maybe the magic wand tool to select within the lines), but whatever you do, it appears to leave a few pixels around the edges of the lines uncoloured. If you use Photoshop or GIMP, something with layers, I might suggest colouring on separate layers, and after using the fill bucket/magic wand, going back in and filling in around the edges by hand. If you just use MS Paint, the same idea applies, just without the separate layers. It may take a bit more time, but for something that's a relatively easy fix, I think you might be surprised how big of a difference it can make in your drawings.
I hope that helps; if not, I'm sorry, and you can just ignore me rambling. I'd just hate to see an artist hindered by something that's more about a computer being picky than his actual talent. Keep up the drawing, I do look forward to seeing more.
