My biggest suggestion for improving the interface would be to try and match Poser's color scheme as close as possible. It looks really bright to me at the moment, and as someone who works in low light I think that could become tiresome on the eyes. As the program is at the moment a counterpart to Poser, matching Poser's dark warm grey tones would make it more visually appealing to me. Though I do understand why you might not want it to match exactly, as if it were merely another of Poser's rooms.
