Sculpting anatomy is best represented with sharp angles, or else it quickly turns into a smooth ball. Once the features are locked in, it's time to smooth and blend together.
Thanks DudeinCA, I will maybe desaturate some of the colors on some of the textures in order for them to blend a little bit better. :) Thanks again for the feedback
Already seeing great improvement in that last piece! :) The chalkier blending is definitely making it look more painterly. Keep drawing and keep looking at references!
predicting it now: the new armour is the extremis armour, and the film will feature part of the argonaut plan. it will lead to the bleeding edge armour and "rescue" in avengers 2.
