I love robots and hate clowns, so this is tough for me. Most of yours is a robot, so I like it. I’d get rid of the clown aspect - I’m not sure how many people actually like clowns. I find them a bit…nauseating. Creepy, like carnies (alcoholic pedophiles who “work” at carnivals). I can’t really tell the difference between the two, other than lighting. The robot itself is nice and friendly looking. Well done.
Edit: Mouth is hard to see. It needs a mouth, so #2.
Yeah, I mean take a look at Bender from futurama, no nose but he has a mouth. since he is a robot, you are at liberty to do pretty much whatever you want with it, a little speaker, or maybe lights, or just a normal mouth, anything goes!
