A while ago a friend drew this character & I’ve fleshed it out in Blender.
Thoughts?
Nice cartoony character, except I hate children’s books(I wrote and published one when I was seven, now I can’t read or write one without breaking out into convulsions). He looks fine right now for a cartoony type character, though if you want to add more detail, you could maybe texture it. (Though as I said before, it looks fine as it is.)
Here’s the original image I was working off of.

I guess if you want to be completely true to the image, you should just texture the JAX-42 thing and hand him a mop.
Nice!
I think he would look cooler if he was just a little bit shorter thou. But I dunno, he looks pretty cool already 
Very nice, I think he needs to be a bit more colorful. Maybe ramp up his colors!
