I really like the base on this huy...and the pose is great...but the paintjob, clean as it is, is really flat. With all the nice, crisp white as the main colour, it becomes really hard to see the edges of the model, or a lot of the other detail...maybe try a 50/50, r even 75/25 mix of Skull White and Ghostly Grey, and then highlight with the white...I think you'll like the result
