Hi, I'm new here and really haven't made any posts, except for a little project in the Unpaid Work section, if you dropped by to see that. But I have been watching all of you and your pixel masterpieces for a little while now, and I thought I would start to get more involved here. I am learning pixel-art and starting to get better, and I thought this would be a great place to learn with you guys.
So, I guess I should show you some of my work...this is the showcase section, after all...

(You might have to refresh to see the animation.
Edit: Well, you might not be able to see the animation at all. Sorry!)Alright, so the one on the top is a chameleon-dinosaur thing, and the one on the bottom is a frog. (Both are enemies for a spare-time game that I'm doing the graphics and some of the programming for.)
Now, I know what you can immediately see wrong with the top one; the legs are coming out of his stomach and don't overlap the body. But like I said, I'm still learning, so please work with me here. I managed a little dithering and chose some interesting colors, and overall I think it looks alright. I started out using a reference image (that's where the wacky colors come from), but then I strayed off too much from the image's look and set off doing the rest on my own.
I'm a bit happier with the frog on the bottom, since it doesn't seem to have any major flaws and the colors are subtle but still stand out. I have another image of it leaping but decided not to post it.
So please give me some pointers on this! I cannot get better without feedback!
