Just some pointers, not trying to be mean. Tank looks good, but some simple things to help improve the aesthetics...
Hide the overflow box, and try to hide the powerheads/returns.
Clean the back glass, and use a background. Things will really pop.
Your aquascaping has a flat look to it. All the rocks go across the tank with no gaps and they don't go higher than half way. Maybe make some caves and pillars, try stacking them up.
Other than that tanks looks good, and maybe you could provide a stocklist?
What are your future fish plans? You have lots of space to work with!
Also FYI, if you use photobucket or another picture site you can post larger pictures embed into the post, which makes viewing them easier.
