Hello and welcome!
You asked for feedback so I will give you my thoughts, keep in mind they are just my opinion. I'm personally not a fan of the wood you are using, they are too 'stumpy' without enough parts branching out. Thus the wood being placed on the rocks doesn't add much realism to me, it almost looks like its just more rocks rather then wood.
Personally I use soo much rock in my tanks I've started collecting it from the wild as its significantly cheaper then buying it. But I know not everyone is willing to do that. For wood though I don't have a lot of good wild options near me so I buy that online or at my local fish store.
Personally I use a thin layer of aquasoil capped by sand in all my tanks now as it saves on how much aquasoil I need to use and, to my eye, makes the tank look much more natural with the sand being visible.
Anyway, just my 2 cents. The most important thing is that you are happy with whatever layout you choose.
