Links to some of my favourite artworks by this Artist:

John Sheppard with, um, wings - a good example of Crys's skill with pencil drawings, also a cute pic of Sheppard looking wry about his wings.

In Depth Examination - a wonderful view of shenanigans in the waters under Atlantis. Click through a few times to see the whole pic for the depth and perspective, then for the close-up of the bottom of the ocean.

Renaissance men and Vitruvian John (NSFW - nudity) - an AU John and Rodney in a Renaissance setting. The first pic has strategic objects protecting John's modesty, but not the second one!
