ok some tips:

the text is too big and distracting. you have two renders of afro samurai which make it hard to distinguish what the focal is. when working with two renders, usually you would lower the opacity which it seems like you did but by putting them next to each other it makes it look like you intentianly made two focal points. also you're effects are pretty random which develops no flow. you should also try adding effects in front of the render instead of just working on a background. On the other hand, for a beginner this is decent. it shows a variety of things that other beginners dont have. good job keep working at it
