Help with my sprites?

[WonderPup]

Hello.

I posted these sprites over at RMN in the hopes I'd get several critiques, but I'm not getting as much feedback as I had hoped. If you all don't mind, I'd like to get some suggestions on what I could do to improve on them.

The original post is here.

In that post, I've been documenting nearly every edit that I've done to these so that you (or I) can see how they have progressed. I feel like they've come a very long way already, but they could still use some work. Also in the post is the original concept drawing for these.

Any feedback would be appreciated. These are my first sprites, and I'd like to get better.

Thanks!
