I'll just re-post my previous comment, since it was caught between stuff.
The tempo itself is rarely the issue, and I can imagine that it can be very beautiful in this tempo.
The problem is that the slower the tempo, the more things has to be clear.
The phrasing is at the moment a bit stiff. I would suggest you to play it rather fast, to feel where the phrases are going, and then go back to your original tempo, to listen after the same long phrases as in the faster.
Also, in this tempo, it gets a bit empty. You voice the melody well, but in such a slow tempo, you have to be very careful with the rest as well, because we now have very much time to hear everything you do, which can be either beautiful, or slightly boring. Now it's, unfortunately, on the boring side. The melody arrives so many times, but the accompaniment is often different.
Not that you should bang out the accompaniment, but you need to listen to the changes more.
Also, you can be a bit freer. Like, a little bit forward and backwards to help the phrases sing more.
Good job in general!
