Thats really good for a first project! I remember when I was starting out I used the same exact asset pack haha
You were able to use all the assets to make a level which is really good. In terms of level design you should improve the skybox / background and add some detail. Also, for a prototype level it showcases most controls necessary which is enough. You should definetly expand on this and iterate on a game loop.
For a first project, you were able to utilize Unity, which can be very buggy and annoying to work with, and implemented all the fundementals a first project should have so good stuff!!
