As deep as you make it

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

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