-make it look somewhat more polished (you can always change this later again)
-add forms
-add more lights, try to find a light source
-add more details, and more lights, (in this case I got a bit confused about the added light from the hand, so asked for advice on reddit, dont be afraid to do that, it really helps)
-apply advice and see what works. learn when to finish… can be hard, always feels like you can do it better, but have to move on eventually
