Gashnak: thank you so much for taking the time to help. I printed out your image at work and have used it as reference material for tonight's sculpting session. You are very kind!
You're welcome. There might be some inaccuracies, because of the unfamiliar angles on some parts and proportions. But eh, it's good to learn anatomy for things like this.
You should send that to GW, some of their stuff make it look like they need it
I kind of consider GW a lost cause, I've got the feeling they fired some good sculptors or hired cheaper, crappier ones with limited artistic ability and understanding. And have just a few good ones do the big selling pieces. It's kind of sad. Some of their work is actually pretty good, anatomically speaking, you have to stylize to a certain extent anyway because of the scale.
On the topic of greenstuff not sticking by the way. I personally find the less I handle the green stuff, the stickier it stays, so washing your hands, degreasing the work environment and such, can help. Also, even though lubrication (water, or whatever you use) and such is nice to make things smooth, you have to be minimal in its application and not have it get everywhere. Just use silicone tipped tools so it doesn't stick to your tools and you won't have to use water for that anymore. I've once looked into using silicone gloves as well, but never tried it.
