Leopard Gecko viv in progress

[MrDreamWeaver]

Hello everyone, i'm new here so go easy on me.
Long story short my lady was trying to sell her Leopard Gecko, and I took the little guy instead. He's a potentially rare morph, and cool as hell.

I'm upgrading him from his tiny 2.5 gallon to a 10 I had laying around from my axolotls...
So my plan is to do a mixture of play sand, and some eco earth. (What ratios would you use?) and i also got one of cavern kits to make my own hides for a fun project with the Ms, and to save money.

This is Casper. Not sure what morph he is.

Here's the hide we made. I'm going to make another one out of mini clay bricks I made. Should I make any motivations? What would you do differently?
