Lighting
Think about how you want your lighting. I took the advice of a buddy and used regular high hats instead of Fluorescent and I think it makes a big difference. Also look into wall sconces to give different subtle accents. A lot of the time I just put on the wall sconces and not the overhead lighting. Softer look and it feels less "basementy".
Just my opinion but fluorescent gives off a cold light vs. putting regular high hats on dimmers.
Good luck.
