Kingdom of Knuffel

I think you look like a wise leader, so you're minimum mid-thirties and more likely mid-fifties.

Early 30's and focusing entirely on your career

Pretty young, around 10, happy that icecream and pegasus exists

maybe 40, grownup for shure and mature, you know how to fit colors so they let you shine, that needs experience.

around 20, fair maid lost in the woods

I think now you are still an immortal; you are a dream-guardian who spins dreams for children, vivid and real, stretching their minds.
So you are very old indeed, numbering years past counting!

I think around 40, you're comfortable with your life and happy in your writing career.

Just now you strike me as particularly mischievous, the type of impish glee on your face that you usually see on the prepubescent! And yet -who would trust a complete child with a weapon? So you must be at least ten...

you look like somone i know very well. she has the same hair and that happy smile in her face. She is about 50 so i guess you are maybe the same

You have a very peaceful air which I associate with people who are much older, but your face lacks any wrinkles! Then again, those are hard to do in KofK.
So I shall trust that air of serenity and say you are into late-adulthood.
