Yeah, sorry, but the guitar sound at 0:30+ has to go. I see the sound you were trying to get, but it just didn't really fit with the other instruments. Also, I try to avoid using detuned instruments unless I'm making a breakbeat that ONLY has that instrument in it.
My other bit of advice is to alternate beats. Make some different beat styles instead of the monotonous Kick-Snare-Kick-Snare. If you're just starting with FL Studio, beats are like the most important thing to learn :). Simply adding hi-hats on the third beat adds to the effect alot :D.
Other than that, the song was generally okay :). The melody was great, just pick different instruments haha. (Sytrus Electric 4 works much better)
Hope I helped!
