Hi Martin!
I would like to suggest cutting down on a few elements of this “crazy-zbrush-monster”-thingy of yours. 6 legs, 4 arms, 6 eyes and so forth. For me that is just too much:scream: I would for example not mind a proper tail instead, and perhaps only 2 eyes and a nasty row of teeth to focus the viewer more onto his head.
It’s got potential, but when you choose to go all in on sculpted creatures such as this, the competition is extra hard. And more work on anatomy and playing around with proportion to squeeze out more character (sometimes with very little effort) is needed I think.
Think it could help out if you also choose a more distinct theme, (like alien, insect etc) and really good all in. Harvest tons of concepts and try adding every good part of it.
Good luck!
