RAGERAGEREAGE
Looking for some criticism before I move on with this sprite. I really think he can benefit from another color like a gray or a black.
Well, the whisker things could be a little thinner. The back legs are always tough, but I suppose you could spread them out a little bit more. With his stance, you'd think they'd be splayed a little more.
Moving on to colors... I'm not really sure about a black, you could try out a grey somewhere if you want. He should probably be a darker, more scarlet-y color on the main body.
The front sets of legs look really good though. I think the fire patch on his back would probs come down a
little further, but then again I can't say until it's done. If it's possible to make his head look a little more pointed in the front, do so, but it still looks good as-is at the current angle.
I'd imagine this is a really tough one to sprite, considering how awkward his shape is to put into pixels. I'm just throwing ideas at you, hopefully to spark some kind of inspiration or make you feel more confident about what you already had planned.
Either way, I look forward to seeing how he turns out.
