Here's a background I've been working on, It's suppose to be a broken down bridge connected by two large rock formations. Underneath the bridge will be a pile of rusted metal, which can be accessed via a large descending ladder and staircase. Please tell me what you think could be improved as I'm new to both Pixelation and pixel art. The piece is obviously no where close to finished, because i'd rather apply crits to it first before going too far in the wrong.
