Fantastic :) Whether you win or not (you will), you are a master pianist. I think you could end up being one of the best in the world if you keep going strong with it.
I also really like the competitions. Years ago, I submitted my "best" song. It did poorly. At that point I made the big step forward by actually purchasing proper software and began working towards creating quality sound. Since that first time, I've mostly submitted semi-experimental songs to get proper feedback. I've never even made it through any of the first knockout rounds for any competitions :S Each failure has been something that has pushed me further. One of my songs called "Bastard" was very well received and frontpaged on this website. That song was actually my response to a certain judge's HARSH criticisms. Basically my way of saying "fuck you". To my ears now, that song has some big flaws, but it is still one of my songs that I am most proud of.
Since then, I believe I have improved myself quite a bit. I still can't get through any knockout rounds, even with songs I viewed as great, but I'll keep trying and improving until I eventually make it through. I don't think I will have the success that you have, but there is something about these NG events that really helps people push forward with their art.
Without the NGUAC and NGADM, I would still be using FL Keys on a Trial version of FL Studio lol. It's all thanks to a random message I got from TaintedLogic in 2016, inviting me to the NGUAC. I view it as genuinely life-changing.
