I really love it. Especially the depth you have created and with open space in the center and the two non-symmetrical peninsulas. It actually reminds me a bit of my scape except I left the middle completely open without the bridge you have. I haven’t changed my scape much since I started about 8 years ago and still love it.
My only suggestion would be to consider your lighting as it relates to the highest points in your scape. If you have a LED bar-type light or T5s it won’t matter, but with pendants or halides like I have, the most intense lighting is to left and right of center. Right now your highest point for mounting SPS with high intensity light requirements is in the center so if you don’t have a bulb above the center, that could be something to think about.
