Great piece here!! I think what you need to do is to broaden your color palette to include more ranges of your base gray. To get more of a space lighting feel, the side facing the light would have a lighter color than the top and the front. The front would be the shadow side. What I did was simply lighten your base gray and place it on the left side facing the light. Then used a multiply layer to just darken the front side that would be in shadow. On that multiply layer you choose a value and paint, then adjust the opacity to get the multiply darkness that looks appealing. I then added stark shadows on the light side to add depth, trying to pick out the faces that would be away for the light as well as what would be casting a shadow. I didn’t do the entire piece but I think it gives you an idea of what you can do with more values and with color dodge and multiply layers. Hope this helps. | Artwod Feedback
