This seems alright but it feels a bit too basic for a cover/remix song. You made this in only three hours? You could spend more time mastering, EQing, and in general adding more of your own personal flavor to this.
The intro synth sounds really nice since it has some reverb to it and sounds funky. The second synth you add in also has slight reverb but falls a bit flat in following up where the first synth left off. The first synth makes this feel a lot like an old school video game rhythm which I like.
The bass line however, is either very low or non-existent sadly. Would help to add that in and have it match the original bass rhythm as close as possible unless you can add in your own flavor as I stated on the synth.
The drums, lastly, seem way too stale for my taste. It sounds like a basic 4/4 beat. Add in some other hi hats, snares, noise filter and mix up how your drums sound, having a bland drum rhythm gets one nowhere.
Overall, not bad for something made in three hours but could be a lot better.
