I've had the pleasure to be part of the outsourcing team for Arkane. The characters were split into different jobs(high poly, low poly, texture) made by different artists. I'm gonna name here the ones from the romanian team: Cristi Buliarca, Mihaela Morozan, Mihai Dobrin, Claudiu Tanasie. You can see here some of my work here. It's mostly low poly and texture work.
