These are good concepts to begin with; I especially like the device thing-whatever-it's-called.
For your Fakemon, I suggest making the evolutions deviate a tad bit more than the level they are at now. Frankly, I can hardly tell the difference between stages 1 and 2. I know how tough this can get because I've had some bad experiences trying to change something too much, until it started looking silly. Things you can play with are just size and different skeletons, and some minor details such as changing it from chibi-like eyes from Stage 1 to normal / anime-style eyes. Also, if you notice, a lot of Pokemon start out extremely small (and round!) and then their second forms are more slender, and finally, their final forms are bulkier.
For your coloring, please try to spill less into the lines and make the lines a tad bit thicker. Also, choose a light source and an angle for your cell shading; in the Skitty, I can't tell which way the light is coming from!
The hand is mostly good, but I think you saved it in the wrong format :P
I'm not sure what's going on behind the index finger, however; the lines should be going from 10-o'clock to 5-o'clock, not the way they're going right now.
To go to the next level, try to emphasize the nails and the digits next time :)
