Well...
This was really good for a first song.
The drumwork was nice, but you need to remember a few things about beats and emphasis. The 1st and 3rd part of the beat are the strongest, and I noticed that you had things on the weaker parts of the beat. Usually, that works fine, but if you have an important part, such as the snare, on it repeatedly, it sounds bad.
The other thing was that the song didn't move except for the drums. You should change up stuff more and keep the song moving.
Overall, this was great for a first song, keep up the good work!
