It looks very nice for a first attempt. Right now, the only problem I can see is what looks like a Hemigraphis species in your foreground. The plant tucked into the wood with the green leaves with purple undersides. It is a lovely plant, but it is not a true aquatic. It can survive submerged for up to a year submerged and at times it is used in scapes to add a bright focal point, but it will eventually die in the aquarium. If you remove it soon enough and plant in moist soil and keep in filtered light, it makes a fantastic houseplant or even a terrarium plant.
Welcome to the planted tank section. Have a look at the pinned articles and have fun.
