I've done roleplays with Igglybuff.

I can see you have several pieces of art here on Newgrounds, but it doesn't seem like you've had much improvement. I'm not sure if this piece right here and others just resemble your style or if you just haven't improved all that much, but I digress. This isn't a bad piece of work, whatsoever. It looks like the actual drawing for Igglypuff, but with just a little more crudeness with the lines.

All of your drawings seem to have some rough lines to them. You'll get better over time. Just keep working on the areas in which you need to improve. You'll get better with each drawing.
