Thanks Dr J, texture wise i'm leaning towards the traditional Grey alien look. Greyish blue, with a slight speckled texture, semi-opac looking.

I've been doing some sketchs at work, naughty but hey I start a new job tomorrow , and I'm gona try the horizontal eyelids for something a bit different.

I'm working on the feet at the moment but the toes look really thin and spindley. Will post a update later today.
