Nice melody with the strings. I like how the whistle was added at :37 to keep it from sounding too repetitive. Also, the keyboard to sub out the strings is brilliant. I'd say the only thing that would need work would be the tempo. It seems a little fast, but other than that it's damn near perfect, man. There is quite a lot going on, but it all works cause there is not too much repetitiveness. All in all, fantastic work.
Btw, thanks for the feedback on my "Futuristic" beat. Much love.
