Overall it looks pretty good. You have some nice places for him to climb and hide and lots of options for him to go where he wants to get the heat and light that he needs.
Is your UV the compact/coil type or is it a tube? I can't tell by the picture. If it is a coil, please switch to a tube as soon as possible. If it is the tube, the 5.0 will be fine for the small enclosure 6-8 inches directly above the basking spot and unobstructed (no screen). When you get the bigger enclosure (which will happen sooner than you think so be ready), you will want to switch to a 10.0 or the Arcadia 12% bulb. That distance will be different depending on several factors on the new enclosure, so feel free to come back and ask for help with placement when you upgrade.
The basking temps should be 100-110 while he is a baby measured with a digital probe thermometer placed on the spot he basks. You want to go by the temps and not wattage for it, so it will be a little trial and error finding the right bulb for your setup. When he gets to about a year or so and has stopped growing so quickly, basking temps can be lowered about 5-10 degrees.
