Les Bursley's stuff is made of pure win. I hate painting, but I like his tutorials...make the hate of the paint easier to deal with.
You may not be getting the same exact colors since Les uses alot of his own self made washes and inks. Also, your computer monitor color may be a bit different than what his models come out looking like. So, you MAY in fact have the same exact look and color as Les' models, but your screen may be a tad dark or a tad light, and it is making your model look different.
