Overall, you've taken a very careful approach to learning this and I love the work you've done so far. My overall comment would just be to suppress the repeated notes in the middle c# minor section, especially the repeated octaves (2:43 - 3:10). Think of the chords almost being the melody you want to bring out - not the repeated octaves.
Specific things? Just a few transitions between smaller sections just have slightly varying tempo changes that seem a little rushed (like 0:55-1:20 just has moments where you rush a little bit for a few seconds and then hold back just a little too much for my liking.
4:33 - 4:45 Bring out a little more of the inner notes. It's pretty damn good, but bringing them out more will just make it sound exquisite.
Hope that gets you started. Overall - just needs to be a tad faster.
Also, memory is a pregnant dog sometimes, isn't it? For some reason I've never had any trouble with it yet I'll head to the shops and completely forget what it is I'm buying.
