Your OC isn't heavily "mechanized". It's basically a normal person with easier to draw face, hand and feet. When people ask for mechas they usually refer to complex stuff like gundam, transformers, macross, etc. You might "scare" a potential artist with your title.
well at some point, i may touch up the design to grow more complex/evolved later down the road. I'm aware its pretty simple atm, but i honestly like that simpliciy, although the fact that hes still technically a robot, even with the references showing how simple he is, most people automatically throw in the "sorry, he's mecha. cant really do those well" and thats the end of the matter.
