3 Jazz Improvisations

Here’s 3 jazz improvisations i did some days ago. One of the is over a modulating major 2-5-1 progression and the other 2 is over major 2 5 1 progressions
I know it’s FAR from perfect, so I would really appreciate some tips to get my jazz improvastion better

I used Gibson ES 335, and my Line 6 Spider Jam III to record

Thanks 🙂
