You have it memorized, which itself is an accomplishment, but definitely some areas of concern technique-wise. In my opinion the two biggest faults appear in the first 30 seconds:
1) Your playing appears tense, and your fingers are like little hammers with very little involvement of anything above your wrist (elbow, arm, shoulder, body). It may be the camera angle, but the opening arpeggios seems to played with only finger-action, and not incorporating any wrist rotation.
2) In some cases, such as around 0:23, your pinky looks completely flat, and your wrist is almost collapsed below the key line. This is a recipe for future struggles with tension as your repertoire increases, and will hamper your playing at best or cause pain/damage at worst. You are losing the natural curvature in your hands/fingers and therefore will have great difficulty in getting a concert tone without straining to accomplish it.
Anything to do with phrasing, pedal, etc. is a distance 3rd place these issues.
I'm not sure who said you should "learn something faster" after Pathetique and Chopin Noctures, but Moonlight 3rd Mvmt is definitely not what I would have recommended. People probably get tired of seeing me say this

but with your technique as it is, I would recommend spending a good deal of time with Bach Little Preludes/Fugues, then Inventions/Sinfonias and WTK. You want to get pieces such as those to a point where your playing is fluid and effortless, then consider moving up to more difficult repertoire.
All that said, kudos do you for posting! Not an easy thing to be willing to hear critiques from other players. Best of luck on your exam.
