reminds me a bit of a hannah barbera character mixed with Bender from Futurama (in a crazy good kind of way, ofcourse).
However, if it's not the main character, or you're seeing it up close, it might have too much detail.

If it's a maintenance bot, it could have a texture with some scratches, small patches of rust etc etc.

It looks very unfinished yet, but i can see this going the right way.
The hands look weird, even for a robot, maybe it should be more in style with the robot, and not so organic as they are now (add more square shapes or something).
The head might be scaled too big, but that depends on what you want it to look like Right now it looks a bit like a teenage boy... (and on that topic, maybe you wanna add some freckles made out of rust in his face, just to give him that character some more).

good start, now go make it awesome by finishing it
keep it up.
