See that dark shadow spot in the middle? I would probably think about putting a 175w MH there or something to brighten it up. It does look a little yellow but, seems okay with the atinics on. Looks like a good start to me.
are you sure those are 10000k bulbs? if so what kind? i have 2 250w 6500k iwasakis that dont look that yellow. maybe the 250w 10000k bulbs are not as good but i also have a 175w 10000k bulb that looks a nice white with a hint of blue.
