Hi, welcome to the forum.
I think the scape looks great, if anything it looks slightly bottom heavy with the rockwork being more substantial than the wood, however when the plants fill in the upper area will balance nicely. There is good height and a reasonably natural shape to the scape, perhaps adding a few more epiphyte plants to the joints between the rocks will soften the transitions and make for a more natural look. Stick to a good maintenance routine and enjoy the development of the scape.
Stocking wise it’s not a massive volume however a group of ember tetras would look nice in there, as would classic neon tetras. Perhaps the deeper bodied embers would work better with the taller dimension of the tank. A species that is calm will add to the natural feel of the tank and allow hours of relaxation whilst day enjoying it.
Cheerio,
