Awesome .. looks good too, you did a good job, if you were to attach it to a piece of plywood painted white or put some kind of reflective material underneath and paint as much of the surroundings white as possible, this will also help tremendously...
The buds are looking nice, keep up the great work!
PS:
Harvest,
I would recommend at least 40w per small plant, the more light you ad the better the results are going to be, in flower I have 130 something watts over two semi large plants and the tops are doing ok but the two plants that are under more light are doing much better all around..
