I can't believe I never uploaded this! I made this back in 2013 as a Christmas present for my husband. The figures represent us. His Chinese zodiac is a Dragon and mind is a Goat/Sheep. I also love unicorns, always have, so I fudged mine a bit by making it more unicorn like but with a sheep like face. I also enjoy the asymmetry- dragon against a unicorn, sleeping soundly next to one another.
My husband loved it. I wasn't able to color it until awhile after our son was born- but another year later I got it framed.
I dunno how many hours, but materials used: markers and colored pencils- used PS to fix a few lighting flaws from the camera flash.
