How to improve his enclosure ? The

He has a heating mat (connected to a termostat) a lamp i have to change for a special one, its a temporary one that heats a bit but is mainly just so he has light during the day, he has lots of hides, a shedding box, water and calcium the terrarium is 130cmX30cmX50cm I feel like he would like to be abble to climb more but i dont know what i should get. I would also like advices on what lamp to get aswell as adding another substrate so he can dig. Thank you ^{^}

Also the plasic plants were better put but he seems to really like destroying how i put them lol
