I agree Guitar, requinto, vihuela, mandolin sounds would make it much richer,
P.s. adding a new composition, made on Latin guitar harmonies and solo nylon requinto strings no pick needed, after that I created the harmony, rhytms styles with bass on irealpro, Latin jazz (Mambo swing) in my opinion created with New Orleans styles offered for sharings YouTube link
