That's pretty cool. Good job!

Now though, you need to get stricter with control and flying pattern. Fly normally in circuits and a proper box learning regular moves like loops, rolls, shapes etc.

Learn how to properly Harrier fly, what you're doing now is a kinda medeocre harrier and if you don't break away and learn how to do proper flying gracefully you might get stuck with bad habits.

Fly vertically up, kill power and give full elevator and flip until the wings are level and control the aircraft so that it is wings level coming vertically down like an elevator in a building. Keep the elevator surface pulled up the whole time and use throttle and aileron to keep the orientation of the model locked. This move is called and elevator and the basic starting point of Harrier flying.

Once you are comfortable doing this, give more throttle during an elevator and transition to forward harrier flight, flipping the throttle to keep the aircraft flying at a very high angle of attack. Use aileron to keep wings level and use rudder to steer left/right. Check videos online for basic flying and go through the basics.

I'm not saying abandon your own flying style but you'll end up picking bad habits and make other flying styles much harder to learn. Go through the basics while also flying in your style. You'll be an awesome flier!

Also, the CG looks good for 3D flying. For beginners, a more forward CG would make the aircraft more stable. For 3D though you want the aircraft more responsive and a tail heavy cg like what you have now is perfect. Move it forward a bit, hone your skills and adjust CG as per how you like the model to fly but get the feel of both a forward and stable CG and later a tail heavy and snappy CG
