sorry for light on light.

Nice colour concept, I just think there's a bit too much negative space, if there were a few dark lines (similar to top right) on the bottom right coming out of the render then it'd be a big improvement.

I like it, I think it'd be better without those two orange spots, on the shoulders of the render. GJ

looks un finished its missing some effects . also im not a big fan of these colors .

Maybe you should go back and add more orange areas to the tag instead of leaving small orange orbs.
