For your first time with FL, this is pretty solid. The composition is great and I could definitely see this being used in a game here on NG.
Your biggest setback here is the sample selection of the drums . Those default FL drums sound pretty weak. Plus, for this type of track I think you would want some video game-esqe drums since this is a video game track. The Shovel Knight soundtrack is a good example of the type of drums I'm talking about.
All in all, promising work!
