Haven't been on CA yet alone visited in awhile. You've really bumped up a notch or two. Kudos for sure.
For color on the last one. One of the few basic things I know about color is usually warm light cool shadow. It's not a universal but it's often the case. Maybe try adding some cooler values in the darker regions ever so slightly and experiment, don't go overboard though since the skintones pretty nice so far. Just a thought.
