Based on a piece by the fantastic Simon Stålenhag: http://i.imgur.com/cdAiIvl.jpg
I've seen a lot of his art online and I really must get one of his art books, he has some really great taste.
Looking back at the original artwork I see a lot of differences, most obviously in the proportions and scale but in the end I think this looks pretty good as is.
I had a lot of fun with this one, used the same basic pipeline I typically use however I get Textools a try this time when unwrapping and I have to say I really like the tools, it's no wonder why they are so popular and I will definitely be using them going forward.
I also got to use Toolbag 3 for rendering on this one and although there are many new features I still haven't tried, the shadow catcher is easily my favorite feature so far, I can't tell you how many times I've had to go back and add some geometry to cast shadows on after having already rendered everything.
