First off, nice snakes.
Now for some advice that you wanted:
I wouldn't keep 2 bp's in the same tank, due it being stressful and both trying to get the better tank spot. I see you have a male & female, so the only time I would really put them together is during breeding season, when they are the proper size/weight. I would also recommend getting something that measures humidity, so that way you know weither or not misting is good. I would also get an UTH, so you can dim the light down even more, or possibly not use it at all. BP's are very secretive and only venture out during night, the log isn't necessary as it would just give you more stuff to clean, and last but not least, you need 2 identical hides.
