Nicely done, Sloane! :D Looks great! I do think that the lineart needs to be darker, though. Lineart should always be darker where there is shading. I can see you have done that, but the change is so minimal you can hardly tell. Also, for the shiny colours, the lineart of the body is lighter than the lineart of the pink on the differently coloured features. This results in a banding-type look and stands out in a negative way. An easy fix is to just adjust the darkness of the lines.

I think they would also benefit from harder shading tones, as the difference is barely visible. It makes for difficult readability. Anti-aliasing also really helps to make larger pixel art pieces not seem so jagged. Additionally, this is your colour pallet:



There's an enormous number of colours there considering both fakemon have only pinks in their pallet. Try to reuse colours as much as you can!
