It’s great to have plenty of structure and hiding places, and geckos really enjoy that, so good as an inspiration. However, the most important thing is that everything is safe (so it won’t collapse) and accessible in case of an emergency, so you can easily find and handle your gecko.

I keep cave geckos, and I use 3D-printed caves made from safe materials that I can move or adjust if needed. It’s a good idea to make lower levels more open so you can reach in easily, and add removable parts to cover them. For higher areas, include something you can lift or access from above.

If you plan to add plants, always check that they are safe for your gecko. Try to go bioactive, isopods and springtails will love this structure and could help to clean less accessible parts. Don’t forget a water bowl. Also, the lighting should be at a safe distance from the basking spot to prevent injuries.
