Some constructive criticism for Eve's base model.
Over all, I like the model but there's a few things that could use improvement.
The shadow clothing (not the worst part imo) - Add more moving colors into the shadows on her body so it looks more like living shadows. My suggestion would be to add some darker, possibly less saturated blue's that move around like the pink parts. That or make the current blue darker and add lighter shades. Don't go overboard though. Her clothing doesn't need to look like a lava lamp or anything.
**Tentacle Spikes - **They currently look like fins on her model. Make them a bit more rounded. Additionally, though not mandatory imo, the textures could use a more crystalline look and maybe a glow.
Hair - Make the hair white and add pink flame particles to it. If you can do green flames for Thresh, I think you can do this for Eve.
That's just my two cents. Keep up the great work Riot.
