i think its pretty nice to see how a certain graffiti develops, just like it was already mentioned.. the mixture with diabolo has never looked bad, just like in "It's tricky" by pranay or the Bidiabolobadu (i don't know the proper name) by M4U!
The bright colours and the taste of "street" as well as street art works everytime, and here it worked for you!
maybe next time, try to link your tricks more or cut it a little faster together, because 7-8mins of just playing around gets boring quite easily...
Looking forward for your next videos! The music rocks!
