OK. Good start. Get all your models done then go for textures, then lighting. Always texture before you light because the light will be totally different if you light a flat shaded model before applying textures to it.
Cork Board: Even in real life, you're not going to notice a bump on the cork board from a distance. Just look how close u had to get to the board to take a snapshot of the bump. Dont kill yourself over it.
Wall Trim (or whatever u call it): The white trim at the base of the walls. I've never, in my life, seen those so round like that. If that's a personal preference, then dont worry about it. Otherwise, try flattening them out a bit. Just scale them in on either the X or Z axis to flatten them and kill the specular on them a bit as well.
Light Models: They look good but need the tessalation brought up on them to get rid of the jagged edges. Round them out a bit more. Either up the spans on them in the channel box or rebuild the surfaces to make more spans.
Keep going on it. Looking forward to the final image.
