I suggest adding a subbass to "Creme de la Creme", it needs to have something low to fill that void (other than the bass drum).
I think I'm hearing side chaining but it's not too clear
The drum beat is weak for what you are attempting, it doesn't go together very well
Also the melody is very basic
But I am hearing that you're making progess
Also, it seems that your rap beats are much better than your EDM songs, I'd suggest listening to Aphex Twin to get a glimpse of melody done right (specifically his song 'Flim'), and I wouldn't be suprised if you've listened to deadmau5. He give an excellent example of song progression and melody. Also, if you want really good FL Studio tutorials and tips, check out a guy named SeamlessR on YouTube.
