On first three, I would compare and contrast model's face with her body - color, lighting, texture. There is expression they give models- "Come WFO" means "with face on." Here looks like face is on like a mask. Also contour and gradations - all highlight on forehead, all highlight on cheeks, all highlight on chin makes look like flat bones. Round, nice bones is healthy and beautiful - the have shading and shadows also. Watch colorimetry. Especially in last #3 snow is turned blue! Snow is blue in nature because reflects blue sky, is not real color of snow. I worked with a fine art juror once who would nix any snow too blue, lol. I also don't see pores. May be the low res but in this day and age nearly everybody now wants pores clean but there.

Thank you for your feedback I will work on the areas suggested. I liked what I did with them but for some reason I had this nagging feeling like something was missing and that it wasn't complete and that I might of done too little or to much thank you this has helped me. I love getting feedback this way I grow as a retouched :-)
