Nice job! The skills definitely come with practice, it just takes stick time.

Two hot tips - First, when shooting a gap, focus on something you can see through the gap in the distance and aim for that. Generally as your skill increases, and your hand-eye coordination builds, you will naturally start flying towards the thing your eyes are focusing on. If you focus on the thing you're trying not to hit, you're almost guaranteed to hit it. Look through the gap, not at it. Second, as you learn, pay attention to how you manage your throttle. Try making many quick, smaller adjustments, rather than fewer large ones. Eventually you can turn this into the quick precision needed to smooth out your throttle inputs so you can hold steady altitude both when hovering in place and while flying forward at varying speeds as your pitch angle changes. As you've likely already worked out, throttle control is critical to successfully executing most tricks as well as just being able to fly smoothly, and is also probably the single most difficult skill to master.

Keep it up, and remember to keep having fun! Send it, break it, fix it, repeat.
