I listened to most of this. Nice writing. A Sonata is based around themes and development. Things of course are looser these days. If sections 4,5, and 6 are to go in one movement, put them together and add some transitions. The theme from 4 should reappear in 6 more prominent. If #5 is the development, change keys, add the main them back in there, etc. A lot of potential though. I've been composing this summer and finding repetition is not a bad thing at all; especially if it is good music.
