That's really good for a first, it's obvious what's going on, and it has been executed well, things you should work on are as follows : Clean up your lines, this means removing any joining pixels that aren't necessary EG : Think about textures, (floor should be more dirty). More stuff, like rocks and skulls around, makes a big difference. If you're going to outline one thing in black outline everything. Practice practice practice :) . Hope to see more stuff from you in the future.
