Cyangmou has worked on my game both as an art director ( he had another artist to manage on this project) and artist (both in charge of the design and execution) and I can only confirm what others have already said:  His recommendations as art director have been invaluable, and the solutions he came up with were very good. The end result was quite impressive despite a tight budget. I had a great time working with him and I am definitely looking forward to working with him again in the future.
