Welcome to the hobby! You're off to a great start.
If those plants with the large leaves are amazon swords, they will outgrow the tank. Also, those frilly plants look to be hygrophila difformis which will also outgrow the tank.
It may help you to do some reading about the basics of aquascaping. The aquarium can be broken into the background (back of the aquarium, inhabited by tall plants), the midground (middle of the aquarium, inhabited by moderately sized plants), and the foreground (front of the aquarium, inhabited by small plants and carpeting plants, which are plants that spread out to cover the substrate). Hardscape materials--wood and rocks--can be used in many different ways to produce certain aesthetics in the aquarium.
There are different styles of aquascaping, including nature/Amano, iwagumi, Dutch, and jungle. The nature aquarium seeks to replicate a scene from nature. An iwagumi aquarium is built around an arrangement of rocks (to certain specifications) and usually uses shorter plants. The Dutch aquarium is based around the aquarium as a garden and focuses on lush plants that contrast and complement each other (it also has specific guidelines). A jungle aquarium is usually lower tech and focuses on creating a lush and natural appearance. This
article shows examples of the above styles as well as others. You can pick a style and stick with it, blend multiple together, or abandon them altogether. They can be great inspiration.
It's also notable that nano aquariums frequently make use of plants with finer leaves and small fish to give the appearance of a larger space. Google "nano planted tanks" and you'll see what I mean.
I hope this helped
