Look at these eyes

This is a young model that I shot this week, I love her eyes. The first shot was with a 5Dc, 70-200 mm F4 L, at F10; 1/100; ISO 100 at 150 mm focal length and was shot was under a gazabo with fill flash, the second shot was out in the harsh sunlight with a 5D MkII, 100 mm F2.8 L at F5, 1/320, ISO 250
What do you think?

watch your white balance as they are different in the 2 shots. Would prefer #1's WB as #2 is too cold and makes her look pale. Also, I know you used fill flash, but if possible, use it off camera as the lighting looks flat.

Agreed with fashionrider. They look a bit flat to me as well.
