Undeniably one of the beautiful pieces of Tyrande I've ever seen. You've managed to put a lot of life into her, it's not like she's just standing there to be looked at (something I see in a fair number of other pieces, even good ones).
This really is a very nice painting. Great job. There several things I really like. However I have to compliment you on the fantastic looking ear. A slightly different take on a night elf ear but very fitting nonetheless. More than anything I think people have a hard time making night elf ears give the right vibe. Yours definitely "feels" right. Bravo, on a lovely job!
