30 Day dino challenge Day 2

I found a nice little dinosaur challenge: [link] and decided to give it a try.
Day two: favourite sauropod. I must admit that at first I almost decided to go with giraffatitan, but then I found this mysterious and massive creature, and just fell in love with it. Amphicoelias is one heck of a mystery for a dinosaur, and I hope that they someday find more of those gigantic fossils of it.

Done with Derwent Pastel pencils on Canson drawing paper in about three hours. And yes, I do suck at sauropod anatomy. xD
