I often tend to... overdo my works. I simply try too much. Here's some practise for that problem, I tried to left it pretty simple and play
with lights... some coloring practise as well since it seems that I have stuck with using same colors every time 'cause mixing different colors is hard.
Photoshop and few hours. Most of the time went with choosing colors, like always.
Basic idea was from game named Dishonored, and I tried to get a bit same feeling like in it. And I still want to get better with environments. Not satisfied.
