And now for the inevitable evil crit. Ok, firstly, my backsprite crit is not as good as my front-sprite crit. The main issue is his beak. Let's look at the front sprite:
That spike thing on the back sprite is much to straight compared to the front one, and the outline is too light. Also, there's a design issue. The front sprite has red spikes on the cheek, while the back doesn't. The fire on the front sprite is wild, while the fire on the back is straight. And there should be atleast a little bit of the white fluff on it chest on the backsprite.
Overall, the backsprite needs some smoothing, just to make it look like the front.
And why is he looking into space like that, in a whole other direction x)?
