I felt the funk, so I had fun listening! I like the sound of the guitar in particular. I think the percussion leaves something to be desired, but I do think you did a good job. (and for whatever it is worth, I don't think using Flower is a prerequisite to finishing this song-- if anything, a different synth might imbue a unique personality into the song (as well as unique tuning that resonates with you))
If this ever got lyrics, I could see myself creating a fan MV for it. Looking forward to seeing you upload on niconico douga B)
