>>31515408What's the concept here, is it "just" an ice bird, or is it based on an actual bird, perhaps one you find in snowy areas, the arctic, etc? It's hard for me to analyze this if I don't know where the design and elements comes from. I do see blue jay in it though, if it's a blue jay given ice powers because it's blue, that's works. Anyway, here's some general feedback.
Suffers a bit from it-just-gets-bigger syndrome, especially from the 1st to 2nd stage, though the body shapes are at least different.
Specifically, I think you need to be more selective and deliberate with your design choices, and simplify the line in general. 3rd stage pretty much looks like a legendary from Gen V, and those are way over-designed.
Pokemon usually have very clear features, and those features typically "evolve" themselves alongside the pokemon. For example, look at the bulbasaur line and notice how the bulb doesn't just get bigger, it actually evolves into a complex, lush flower. That's just one example of many though, as often times there are also features that are added but sometimes even taken away from stage to stage, such as Wartortle having darker blue skin and the ears/tail that look like waves/foam. Changing things up from stage to stage makes the pokemon feel fresh as it evolves, and the challenge then comes in making it feel clear that the pokemon is still evolving to its next stage.
Here, generally the features that are on the final stage are already present from the start, and they don't really change a whole lot, the features themselves "just get bigger." (The ice being the only exception that's exclusive to stage 3, as it should be)
I might for example, completely nix the nipples and the feather on the head of the first stage, keep the 2nd stage relatively same, possibly switching the dark blue and light blue with each other (here i'm just taking a page from Wartortle) and then rework stage 3 to bring out the ice wings in a more creative way.
