I haven't listen everything (sorry), but it seems to me on the rhythm aspect when improvisation are a beat messy when regarding to the strong vs soft beats... okay let me try to explain this in a different way... there is not a consensus between the notes you play and the accentuation 1 2(!) 3 4 (!) and the tension and resolution for consequence. The way you star and finishes your phrases regarding to the bar beat...
Sorry i can't explain better
