Beautiful to see how u don t copy your reference but rather use it as a source of inspiration. U made her more beautiful then she already is in the picture. Thats the way people schould work on HQ pieces imo.
I don't think u can compare those two: Marko works for Marvel wich has to be verry dynamic. I don't think Elwell need such dynamic poses for a book cover...people like Marko D don't do it, so it seems to me more like a clumsy crutch that ends up producing stiff images.
Nothing very wrong with that cover but it looks always too posed and stiff to me.
And besides I'm sure Marko uses refs also from time to time. It would b foolish not to do. In the sence that making use of refs. (like looking in a mirror for the hands or a global pose) saves alot of time...
Bravo Elwell! *****
