Hmm, everything sounds sort of samey. It sounds like Impulse synth, Minimoog, and a combination of others like Messiah and Lounge Lizard. But I do like how you've mixed your percussion and bass. I just wouldn't quite say this is your average house. Most house has a lot of modulation on the leads, at least the House I've heard. I'm no expert, by far. Do you listen to house often?
You may want to apply a master limiter to fix the loudness problem. It will prevent most distortion and compress quite a bit. I master limit all of my output tracks for the sake of just preventing clipping and adding volume when needed. You can automate this in DAWs like Mixcraft. I also think you could benefit from a stronger kick. Dubstep style drums in the middle were also an unexpected change, at least without wobble bass.
Overall I like your original compositions a lot better than covers. Just seems like you bust up in the eardrums and get shit done more without trying to emulate a particular style or song, if that makes any sense. Anyway, keep plugging away at that DAW. Genre experimentation is your friend! Looking forward to seeing/hearing more from you!
