AACG: Blue and Brown ATC

For this ATC swap, we're using only shades of blue and shades of brown (sand, cream, and not-quite-white are shades of brown). I get so excited when faced with a challenge...seriously, the "challenge" swaps are my favorites. To make a lovely little work of art including certain specific elements, and not have it LOOK like those elements were required ...well, I revel in that. And I hope you do, too!
