Great work! The rocks threw me off too until I read why they're there. The right side of the tank is really working. You're totally on the right track. Here's what I think:
As of now, your layout is split right down the center of the tank. You may want to shift the negative space over to the left a bit (the reason for moving to the left and not the right would be to make the right side the "heavier" side, which would justify why your wood is so much bigger on the right than the left).
Agreed the bright green is too much for this scape.
The left side of the tank, as well as the farthest left part of the right side, needs some tidying up.
The green crypt on the left is a great accent to all the fine, needle-like leaves. I'd maybe work with that instead of anubias.
When you get the center's negative space opened up and settled upon, consider adding some more substrate to raise the height in that one spot to give dimensionality.
Nice work
I have so much to say because I think this is a scape that, with a little tweaking, has some great aquascaping contest potential.
