Brian is right. You are doing great, wow! It sounds so hard and you are doing so well. I am glad you blew the end and thus showed that it was actually played by a human being
I'm not familiar with the piece itself, so I listened to yours first before listening to professional recordings. Personally you've labelled it accurately, it's a WIP, which puts my brain at ease (we've both heard some "completed" performances on these forums not even played at half tempo!), you're under no illusion that this is not yet ready even for an amateur performance. (although as a competition winner, can we still consider you an amateur?! )I'm not going to try and break down different versions and compare them or pick yours apart piece by piece, I have neither the knowledge or experience to do so on this particular piece. As you know it so well, it's easy for you to feel like it is worse than it is, to pick up on every little detail, which is definitely a good thing. To hardcore die-hard Liszt fans they may laugh with you at the parts you consider terrible. However, apart from the ending, with no prior knowledge, I listened to your performance without questioning probably 90% of it, so it was convincing never the less. It sounds like the only thing left to work on this piece just requires patience, working on efficiently moving around the piano, knowing the piece fully and minimizing any unnecessary movements. It's going good so far.
It's really truly not that bad. Just keep it slow and consistent like that, and don't speed up faster than you can handle. This piece actually doesn't sound that bad at slower speeds
in fact it doesn't sound, that you're playing what Liszt wrote in the rh.
