Initial quick sketches of the character concept!

The yellow and blue are good colours together! He definitely looks electric!

Some quick thumbnails, which one is your favorite?

hahah this dude's got a ton of personality xD just be careful with how you use saturated colours, I'd suggest toning down the yellow a touch so the blue can really have impact or vice versa


I added some color to my two favorites! Let me know what you think!

I prefer the one one the right. Maybe find some pictures of someone using a sledgehammer as reference.

I really like the first one, a lot of tension and suspense in that pose - lots and lots of potential for a beautiful gesture too, it reads really clearly! I think it also shows the design of the hammer nicely too, although both thumbs are good for different reasons

Update! Blocking in things; probably need to fix color saturation too
