Great tunes!
If I can make a couple of suggestions..?
Try to make sure the lead sound carries the same level and type of reverb that the backing has. It will help the solo bed in with the backing, make it seem like they are one, not a backing in a large room but the piano in a separate small room…!
You might also try the octave or double octave doubler preset in the Melody Intelligence section (or whatever your arranger calls the thing that adds a chord to your solo). It adds power and definition to a one note type melody line, and is a common pianist technique when playing just one solo line…
And finally, as I find myself saying so many times, try turning DOWN your lead sounds! For starters, especially after you take the above advices, your solo sounds like part of the band, not something tacked on top. And secondly, faced with hearing the drums and rhythm so much better, you may find yourself locking into the rhythm of the style better. You’re rushing a bit here and there, and I’m sure you can get into the pocket a bit better hearing the groove. Dragging a melody a bit is often cool, but rushing almost never is!
Turn up the band and RELAX! Let yourself be a part of the band… 🎹😎
