Hey Sting. You've got the beginings of a great MOC.
I agree with you on liking the use of lattice windows, but I think you might of gone a little overboard. The two white ones towards the top look good, and the two smaller yellow ones look nice, but the yellow one in the middle, that's sticking out a little, IMO, looks out of place, and just sort of clutters up the middle.
I think the same about the top two windows on the left side; the idea is nice, but I think the windows are too close together, and looks a little messy. if you would move them apart a little, it would probably look better.
The colors look nice, but if possible, I would try to stay away from using black.
Overall, I think it's a nice creation, but with a little work, I think you could make it better. :-)
