Bird Celtic Knot

So this bird comes from the folio 2R of the Book of Kells.
I am teaching myself Celtic knots technique and this one turned out nicely.

This was also the opportunity for me to play with color tones. I am in the process of creating color palette based on pictures I have taken. The hues used for this knot were based on a picture taken at the beginning of the fall around a lake, hence the green which is not as bright and the soft ocher and yellow. I found that the tones were matching well with the Celtic style.

Knot done 100% by hand and digital coloring.

I had a hard time decided which category to put that drawing in...any recommendation?

Feel free to comment. I comments! ^^
