Hello Adarsh, it is very important to see dreams, you have your goal, you just need to work hard for it. for landscape/street I would suggest you to watch 2-3 videos on youtube, search for Basic rules of photography (landscape)
Compositions of photography you need to watch these rules/composition 3-4 times so that you remember how to compose a picture whenever you're shooting. I am sharing few rules below The Rule of Thirds, Framing Images, Geometric Shapes, Diagonal Lines.
