This is so cool. I like in which style you draw the characters. It reminds me a bit on the style of "Disney's Rapunzel" - because the of the wonderful eyes. I also saw your picture of Audrey on your Deviantsite (also pretty cool!). I like that style. It has something special on it
I was never and I'm still not a fan of Diana, but this is a beautiful picture of her. It's characature-ish, but portrait-ish, an interesting mix in-between and it works amazing! : ) Wish I could have a portrait done like this, lol.
Even though this is a characterized version of Di, you achieved the undertaking of her well-known features so that I was able to recognize your portrait of her instantly even from the thumbnail. Your execution is lovely.
