The prelude is well played, though I find the dynamics a bit exaggerated.
The 1st Invention sounds too dry, I'd play it more lyrical, the staccatos a bit heavier and not so detached. The tempo needs improvement, you speed up at bar 3 and you slow down in the hard spots.
Invention 8 is the best one, you bring up both voices clearly and equally, but you also slow down between sections, maybe you should connect them a bit more... or maybe I'm being too picky

I haven't learned No. 13 yet so I can't comment on that one. I wouldn't be afraid of slowing down more at the end of all the pieces btw.
