Looks very nice.
If it were my tank, I would consider moving over the stump that is centered either left or right. A lot of the more pleasing aquascapes use the rule of thirds, just like in photography. The centerpiece of an aquascape looks better, in my opinion, when it is not perfectly centered.
Of course, what really matters is if YOU like it! You are the one who has to look at every day
Overall though, very nice. I am usually not a fan of non-planted FW
tanks, but you have done very well in making it look natural without them.
