Nice! Although, the Java Fern and Anubias in there prefer not to be planted entirely. They will die if the rhizome is under the gravel, try pulling them up a little bit.
I do recommend getting a heater and internal thermometer so that you can keep the water temperature at least 78F. It might also be worth it to cover the back of the tank to keep the possible stress level lower (unless you have a white background already on it and I am totally missing it).
Nice tank. I would also add some floating plants. Water Sprite (Ceratopteris thalictroides) and or some Riccia Fluitans. My Betta loves her floating Riccia mat.
