I think you're in dire need of some more realistic samples if you want to continue down this path.
I think you could invest in some better VSTs. I can tell you're using VSCO2 or something. Consider BBC Symphony Orchestra Discover which is either 50 dollars or Free if you fill out a survey. Because of the very poor quality of the instruments, it's hard to give you pointers on the composition itself. It seems fine, if not a little repetitive/derivative. I do like the drum kit though, that's cool and different.
If you can't afford new samples. FL Studio has tones of shit to mess around with. I think that you could maybe take your orchestral compositions and turn them into more electronic, better sounding songs with that distinctive orchestral structure. Consider it!
