I am a big fan of this technique.The first time i saw it was from you video and it really took me by surprise:) I think you can do a lot of complicated artworks, having multiple colours, playing with shapes. It is very interesting and i think i will try it also myself when i have time in the future:)
You're very right there, acrylic painting is so versatile. I'm still trying out all the different techniques at the moment to get a feel of things, that's why everything is still in a mess.
I hope you do try it some time, it is very relaxing as well.
