Species idea?

(i've never done an actual critique before so sorry if i fail miserably.)
I've gotta commend you on originality here, you've really got a unique look going here for for species and it's just so.. new, yknow?
The back legs seem really heavy and the front legs seem too light, it's like it could just stand up and be bipedal if it wanted to, which I'm sure you weren't aiming for.
I think it's also because of how you did the toes. Which are cute, by the way.
The fluffy tail, I dunno. It's really off. Maybe the shape, or the length, maybe both? It could just be different. I dunno how to describe it.
The fluffyness around the head and neck makes it look like some kinda sheep and oh gosh I can't handle the cuteness ;_;
Anyway, I encourage you to slap some colors on there, let us know what kinda patterns they have, etc, and I'll probably make a better crit.
