I do like the pose on the second one alot!! Some things I noticed that may help:
Be sure the model's make-up is applied lighter, think day make-up. Out side light can be unforgiving and really intensify the prominace of eyeliner, blush and lipstick. Keep it soft and natural as possible and blend, blend, blend!!
It appears that the light is causeing her to squint. Have her close her eyes, relax forhead, and open on your count of three. May take a few trys to get it down, but it really helps with out door light.
Watch the wind. It can be used to your advantage, but be sure it is hitting her hair in a non destructive way. In the last shot, it causeing her style of bangs to fall apart.
I think the lighting was great, choice of attire wonderfull. Keep up the great work you two!!!
