I hope that you will try to improve that picture, because i like steampunk quite much. But right now your picture is rather boring. There's a lot interesting objects, but all of them are scattered throughout scene without much logic and doesn't tell a story. Main character is showing her back and doesn't stand out of the picture in any way. Lighting is flat and uninteresting (underexposed too). It's hard to tell something about materials in such lighting, but textures seems good.
Please keep on working and try not to focus on getting very clean render too much, but rather try to raise artistic value of this image.
