>>36149286That sprite is very obviously based off higher-res artwork and it's pretty jarring. Add a bit more punch and polish to it. For example, in the artwork you posted
>>36149320 the black on its back is more triangular, like Zapdos's wings, while in the sprite, the triangle shape is much more subdued and it's easy to mistake it as just some normal fur pattern.
Also, your colors are way too saturated. It hurts to look at. I made a quick lazy edit, but I think what I did is too down the Gen 6 route. Hopefully you can find a nice balance.
