I really like your build-excellent job with the P.E. Sometimes we have to try something "weird" just because...
The only constructive criticism I would give:
The colors were a little dark and the yellow really looked "yellow" rather than a buff or sand color.
The wash was a little heavy. I used to go heavy on the wash and now I use cotton swabs and a paper towel to soak up the excess. You can always add more later but it's harder to take it away.
Thank you for sharing a great build.
