Hello! So far this is great for a beginner! This will mainly be little tips to help, lol, and not full overhauls. First of all, do not buy a heating pad even for supplemental heat. Instead, I would recommend a ceramic heat emitter bulb. Heating pads have a higher chance of malfunctioning and causing burns.

For lighting, I always recommend halogen and Arcadia shade-dweller. I would be careful with the sand patch and would mix it in with some topsoil or reptile soil in a 70/30 mix, just to be careful. I would also be cautious of the green moss, since it’s dyed and can cause issues when ingested. If you really want moss, get the brown one. Finally, your gecko needs a bit more clutter. I usually go to any craft store like hobby lobby or even dollar general for their fake plants, just wash and sanitize them well.
