How do you manage to get the substrate to stick to the walls of the tank so that the plants grow horizontally in #8?
Hate to sound too critical, but improving your photo skills a bit would help us comment on what we're seeing.
I think the rocks are a little too busy for my taste. Too many different kinds. The reddish main ones, little round black ones on the R, a round grey one on the L, a jagged dark rock or piece of wood further back on the R.
The red ones will most likely look far less bright over time, but flat pieces like that take up a lot of planting space. I wouldn't be surprised if you lose some of them over time to free up more room for plants.
Plants look pretty healthy, but can't really see the scape until they grow in.
One thing I'd suggest thinking about changing is the 2 biggest rocks. They are right in the center - the clear focal point. That can be a difficult arrangement to make appear pleasing. You may wish to search "golden ratio." I don't see any other clear foci other than perhaps the val R of center front. You have a couple of red plants in there, but I can't really tell what they are or how they will play in the scape until they get a bit bigger.
Meanwhile, the "horizon" is pretty much high all the way across, tho the najas (I think) in the back will be wispier than either end. At best, you have it high on both ends, and lower in the middle where your focal point is.
To be concise, I think the layout is a little confusing, busy, unfocused. Might benefit from making some clearer decisions about what you are trying to go for.
The foreground looks like my dwarf sag, but I'm no expert. You could use a few more plants if you want it to look like a carpet. And I'm not sure it ever will - and if it did, it might be a little tall for a medium sized tank like yours. It will tend to collect detritus, so pay attention to it during water changes as it fills in. And I don't think your tank needs anymore green - at least not that shade and leaf texture.
Please don't accept this criticism as anything other than constructive, and thanks for sharing your pics.
Everything looks very clean and healthy.
With a little tweaking, it will be awesome!
