Here’s my final image! I like how this turned out for the most part, although I may go back and make the frame more realistic, I can’t decide. I may also add reflections to make the screen look more like glass, but I can’t decide how to go about that. I drew the monsters in from scratch, and the frame is a modified version of oneI created using “render frame” (Filter>Render>Picture Frame…), but the original images for the background and the sludge textures are under the cut.
