I was fortunate enough to write an article on gamesartist.co.uk about my M2 Browning Machine Gun "Ma Deuce", beginning with the process of collecting references and concluding with how I used Photoshop to finalize my renders. Many thanks to Alfred Golovanov and the Games Artist team for this opportunity.
