Starting off, this is one of the most common progressions of the EDM genre, the ever building 4 chord staple, so to speak. This one doesn't sound bad, but the opening synth is a little generic. Maybe mod it a little or change up your oscillators. These sounds were more prevalent in the 80's. The synth around 1:10 sounds a little more mature.
Overall, the track so far is lacking a little bit of punch. The volume and breadth of frequencies just isn't there. Instead here are the staples of house in rhythm, which is not necessarily a bad thing. I like the transition around 2:20. It's very mellow and catchy. Could've used a lot more punch before it.
2:50, we're back to the generic arping synth. There is also a total lack of hi-hat here. On the positive side, although there's little punch, there is also little to NO distortion, which is good! Your melody is catchy. I just think it could use a bit more volume, a beefier kick and snare, maybe a little side chaining.
The synth around 3:50 sticks out in a not so good way. Could use more modding/FX. Also, the return of the main theme at 4:34 sounds like a loop gone slightly off. Completely caught me off guard. Fade is nice though.
I sense you may be pretty new to producing, but don't give up. There are good things happening if you're getting this far on your own. Don't get discouraged, and don't ever stop trying. Things will get better in time, and you'll have more samples and better DAWs to work with. If you have any questions, I'd be glad to help.
Thanks for the request!
