Sebastien Larroudé is one of my favourite concept artists working today. Formerly a senior concept artist at Eidos, where he worked on Thief 4 and Deus Ex (we actually featured some of his DE:HR work previously here), Larroudé - aka Rainart - now heads up Steambot Studios, a collection of brilliant artists that includes the likes of Thierry "BARONTiERi" Doizon.
This gallery features a selection of works, both professional and personal, encompassing not only his time with Eidos but other projects as well like Tron Legacy (the actual movie) and Steambot's awesome coffee table book Exodyssey.
You can see more of Sebastien's work at his personal site.
