First off, the lead synth used is really annoying. I don't like the way it sounds, it's too loud and pingy, if that makes sense. The remix as a whole is muddy, especially when the fake guitar comes in. Everything is crowded together, the bass needs to be much lower, it gets drowned out quickly. The drums are in the background too much and lack strength, the timing also seems off. The fake guitar just doesn't sound good, it needs some eq, or maybe even a different sample. This is a good start, but it's in a early stage. This needs a lot more work.
By the way, I hope my critique doesn't bum you out. Just keep at it, and don't give up.
