I love those rocks.
Though i do believe some pebles or even some smaller pieces of the same rock would have been able to add some extra detail and maybe even help keep the substrates separate.
That said i do like it.
How long did you do the dry start?
Did your wavepoint unit die on you? I have got one just like that for about a year and half now and i am using it in a tank very similar to yours in size.
That unit is overpowered for just 23 lts, you'll need to get the balance really right not to have algae issues, been there.
Will check for updates as it will look great once its grown in.
