cloakingturtle, metalliandy: Thanks guys :) I have started working on another piece which will be a part of the scene. It's a border piece which will separate the walls from the floor. I'm looking forward to your crits guys :)
i won't agree with cloakingturtle, excuse me. it doesnt look solid. you should nail main shape first, before start adding details. forget about alpha brushes before you'll have overall silhoette and general shapes and flow.
