Nice work! I am a big fan of a green undercheck, especially ancient and/or weathered hues. I think your creation is very handsome in that the mild tone of the yellow stripe (3 threads?) is visually harmonious with the 'lovatey' green undercheck, while the cool blue and woodsy brown stripes provide a tasteful contrast in the overcheck. If I were not aware this was a recent creation, I would think this an ancient tartan. Again, very nice work - would very much like to see it woven.
