How bout.....everything?

all of the above ??

Both faces and anatomy would be really helpful

I'd love to see a process tutorial or colouring tutorial explaining how you create.

Realistic crap & since i havent really seen you do that, maybe juuust....boys, or animals? I suck a little bit at both ;D

I must admit, your art is awestrucking, I admire it greatly!! It feels me with joy and leaves a smile on my face, but what I admire even more than your wondrous art is your great ideas.. Specially how you can turn even the darkest of moments into such a memorable piece!! Often I get lost in my own pains, and for you to create crystal castles and a beautiful maid reigning it, regardless of it being 'just a small pain' to a 'near-death' pain... I would be the happiest with a tutorial like that!! Ehe, but in the end I know you'll just do the right tutorial eitherway..
Still, thanks for all your beautiful and inspiring art, Blue!! I cannot thank you enough, so instead I'll wish you a magnificent day

Lighting!
