Is the thread still open?
If so I'd love to request a picture of my character Jack Frost. I have a reference pic to use, but you don't need to make him look EXACTLY like it. I don't have any pictures of him in actually though, just descriptions. He has a human form, a sort of powered-up form, and then his true form. Whichever interest you the most (all three might be a little extreme unless you really want to) I'd absolutely love.
Human descript:
His hair is very light blonde, nearly white, cut short and close to his head. His hair sat on his head in a messy, chaotic manner. His face is in general very handsome and youthful. He had bright blue eyes, like sapphires, that tend to be quite expressive. He is 17 at the beginning of the story, so that would be the age you'd want to draw him. Jack's personality is very playful, excitable. Almost like a little kid. But he's also very quick to change moods and here is a line in the story to accurately describe that. 'I can be playful and fun, just like winter can make children feel. I can be mysterious and beautiful, just as nature is. But I can just as quickly grow deadly, wrathful, beyond the control of any man.'
Powers Form descript:
Jack’s eyes were now a very pale blue, nearly white. His skin tone, which had been a healthy, rosy color before was now as pale as death. His lips were a faint blue-purple. His hair had lengthened out slightly, falling a few inches past his shoulders. Now, instead of being a very light blonde, it was almost completely white. His fingers, when he lifted one to point at her, ended with two inch long nails...frost was steadily creeping out from where his bare feet touched the floor.
True Form descript:
The creature called Jack Frost stepped forward in his full glory, as the room became a block of ice in no less than two seconds. Three inch long fingernails, as sharp as blades. Long hair that fell to the middle of his back in a chaotic, snow-white cloak. Skin so pale it was the color of death, blue-purple lips pulled back in a silent snarl. Eyes that were ice-blue, with slitted white pupils and sharply pointed ears screamed that this humanoid was far from the fragile powerlessness of humanity. Faint, white tattoos, like frost upon a window, covered every inch of his body.
I apologize for the wall of text. While the color of things might not be helpful for drawing a sketch, I wasn't sure so I thought it best to include it.
I'll include the sort of reference pic, which I feel captures the general look and feel of Jack's personality. The eyes are different colors and the pic is in black and white except for the eyes. But even so the character as a sort of flirty and mysterious expression and this is how Jack would look in his Human form.

If you are no longer accepting requests, I understand. I would just love to see Jack truly come to life and your manga-style is the exact way I envision all my characters as I read and watch manga and anime so often it's a bit unhealthy, I suppose.
Anyway, as everyone on this thread has said, you are an amazing artist! Your work is absolutely beautiful. As some one with low self-esteem myself with my writing skills, I understand all too well the feeling that I'll never measure up. But I'm serious here, your art is wonderful.
