Hello Andrianna,
Wow ... you work is wonderful, great use of colour - truly brilliant work!
And you raise a very interesting point about artists revisiting and reworking old pieces... I agree you can make something totally new from something that is old! I am actually a musician with many unreleased works to revisit and rework myself (when/if I find time!) - though completely fresh inspirational work is my preferred modus operandi.

You can find some of my music here: https://choon.co/artists/icedrum/

Upvoted and resteemed :D
