FL Mobile? Absolute madlad here :P
First up, kudos for working in a screwball time signature and making it work. I've rarely adventured out of 4/4 and 3/4, so I can respect that.
I'll give you the pass on instrumentation since you're working on FL Mobile, but I'd love to hear this if you were to transfer it over to FL Studio and go all out on it.
I'm loving how complex your score is on this, I can't quite put a finger on the key you're working on, but those big sweeping arps and progressions feel pretty damned nice, even in the chips.
The whole score is pretty solid except for 2:15's section I feel, it just seems a little too quiet for that one bit, almost like there needs to be a subtle pad or something there to pull it together. Granted, this may be a software limitation (I'm not super familiar with FL Mobile, I work with the full DAW), but adding something to ease the silence in the background may help out nicely.
On the mixing side of things, I think the reverb you're using on your kicker might be a little much. It just seems like it's just adding noise to the mix as opposed to adding anything of value. You could probably source some of that reverb sound elsewhere in a more subtle fashion, but on the kicker it's just a bit much.
Overall, I like it, I can appreciate the unconventional time signature and what you were going after here, and I'd say you did a good job on it.
Again, I would love to hear this brought over to the full DAW and going the distance with it <3
