Hi Beth!
I like the addition of the BVs. I agree the lead guitar is a bit too up front, so dropping the volume a tad could help. I like the style of the lead, so not suggesting ditching that. Regarding the ending of each guitar passage, once or twice I have allowed the lead guitar to play into (overlap) the bars the vocals start, find an appropriate place to cut that isn’t mid lick, then faded this section that overlaps the vocals so that the transition is smoother. I experiment with the length of fade, and if RealBand supports different fade types (straight, concave, convex etc.) experiment with these also. This might make it less abrupt.

A very cool song, so I hope you continue with it!
