Just get more elements in there. Now it's a bit empty.
Fill the drums up. Just get a break you like, cut of the low end and bash it on there. (with a bit lowered volume ofc).
And a good mastering is not needed to just put on soundcloud or for people to listen too
As previously mentioned earlier it needs a little more depth but the good thing is you have lots of space to add more elements which just means more room for creativeness! I liked the chords used in this track it reminded me of a new track by Koven. Go have a listen to Koven - miracle drum & bass version maybe you can get an idea of what else you can add to your track as it has a similar breakdown keep it up!
