First Project Feedback Please

Hello, i have just made my first Render in blender, i am real new to blender, i started working with it today, followed a tutorial to make sculpts, and i sculpted an Imp face, as known from Runescape if anyone knows. If anyone would like the .Blend file to see from closer.
I would love feedback, good and bad, always welcome, where here to improve our skills, am i right?

how about at least adding some background, like a resting wall or ground? Playing with materials a bit, light setups…

haha, if i only knew how to do that, let me find out how… or tell me how i make these textures people apply to their projects… i have Gimp (I use ubuntu).
