If you like how it looks and it will provide enough light for the corals/photosynthetic species you're planning to keep... then that is all that really matters.

Personally, I like the look of a lower profile scape, and yours looks great. There's lots of open space for fish to swim and corals to grow into. The only suggestion I have is to reduce the sharp angles and flat tops. If you could get more curves and less angles I think it would look more natural.

Sounds like a great system you're setting up. Be sure to get start a thread to document your progress in the Member's Reefs area.
