Looks good.
Regarding lights - this may totally sound odd and I don't mean it offensive anyway but I would have thought the cord from the lights to drive you nuts. I'm coming at it from the angel of your attention to detail and cable management.
In fact, I'm somewhat the same way with cords and wires. I love pendants and have some in our kitchen. However, has I am currently designing my tank upgrade I ended up going the route of an adjustable shelf to hide the lighting n rather than the pendant. I couldn't figure out a way to solve my cord(s)
Tank looks really good has does the sump, house, and everything else you do
Sometimes I feel like a stalker looking at some of the photos people share because I'm like oh, nice table, or counter, or something else they have going on. One time I found a tank owner that had a picture from the same photographer and gallery hung on his wall. Small world.
But great job.
