Thoughts on this setup please

Hey guy's and gal's I am setting up a Mr Aqua 7.5 gallon cube for my wife to have as her own personal reef tank, the tank will be setup on her desk at home so that she has something to look at while she is studying and taking her college classes to become a radiologist.

The tank is going to have Maxi mini's, Zoa's, mushroom's duncan's, acans and a few other LPS and softies...The tank is also going to house 6-8 Sexy shrimp and maybe a pair of gobies or clownfish, I am thinking some of the ORA blue neon gobies, or maybe a pair of yasha gobies with a pistol shrimp

This is what I have planned for lighting, please let me know what you think
