I've seen a few things using tea, and I'm liking the coloration it gives. I love owls and first thing that came to mind was the expression of something being a 'birds nest', or all tangled. Perfect birds to be tangled in.
I love your style, it's amazing. With each piece it's really different but you keep a really sweet almost misty style. I'm always interested in how artists draw their hair so i love this, plus I love owls. Nice little detail to add the hearts. Just really really beautiful work.
