Welcome to the forum and the wonderful world of snake keeping!!

Your setup looks ok, just a few thoughts:

1) you may want to add some more clutter. BPs rely very heavily on security, so adding a few more fake plants may help.

2) again, security related: you may want to "black out" the back and sides of the enclosure. You can use cardboard, dark construction paper, commercially available tank liners, or... I personally use 1/2" foam board insulation. This also helps with humidity and heat control.

3) I see no mention of a THERMOSTAT.
VERY IMPORTANT: ARE YOUR HEAT SOURCES REGULATED BY A THERMOSTAT???

4) It is also often suggested that you have 2 identical hides, one cool end one warm end. This helps the snake thermoregulate without choosing security over proper temps.

5) as cool as that skull looks, it's actually dangerous to your snake. They can actually get themselves wedged in there. I've seen it happen too many times.

That's all I see off the bat, but I can't stress enough how important a THERMOSTAT is...
