Looks great. Can't have too many plants or sticks imo.
One of my temp set ups is very similar, an old fish tank with half mesh, half perspex roof. Houses a female brevicaudatus. What i have done to help with any drainage issues. Is to put a small quarter of an inch thick piece of ply, under back end of tank. This raises it up & any excess water collects at the front of the tank. I then just syphon this off with a piece of silicone tubing when required.
One piece of advice. Watch very carefully for any stress/aggression/territorial behaviour. Especially if they haven't been housed together for any length of time. I have found brev's to be extremely aggressive & territorial & have lost a couple myself, even after a few months of living together. Seemingly very happy, feeding/drinking fine one minute, then next day gone. Not lost any that are housed alone (of any species) though.
What lighting are you going to provide? Agree with NHenn, they really don't like to be too warm. Personally, i just use a 2 or 5% compact uv bulb, raised a few inches above the mesh section of roof.
