It ain't bad
Though these sounds are pretty common as far as techno goes- so it may not be bad, but it doesn't feel particularly SPECIAL.
Maybe tweaking with filters and effects to make the synth sounds sound more unique? It sounds right now like a lot of presets and while that is not bad thing, it just sounds like something we've all heard before.
When it comes to FL, most of the unique sound is not going to come from instruments, but what type of filtering you give those instruments. That doesn't mean go crazy however; it means finding what works.
As far as the melody is concerned, fairly safe stuff, but nothing grating and the track is generally well-put-together.
Keep at it.
