Not the best shot ever, but the best work I have seen in WEEKS! This is my most favorite work of you by far for now <3 The softness, the colors, the emotion, the feeling, the story behind the expression...it is amazing. For technique, Ella, this is 'incredible'... You capture just enough to make the picture work nothing is distracting and nothing is erupting the subject... Impact...well honestly, I always found you the pretty one, but Kathrine is gorgeous here (yes also in more work), but this fits in my wildest romantic movie dreams, she is breath taking with just that you can see here...a truly magnificent shot of her (compliments to the model). The only (and only only) thing that I feel that is not fitting well, is the canvas...the proportions... A full body shot was maybe not possible (lens mm??) or you cut it weird...just a small thing, nothing mayor
The model is gorgeous, the expression is perfect and the makeup is nicely done. The color and the light are really nice and the background is clean.
I think the problem come from the composition, there too much empty space on the right and my eyes keep staring to that space instead of the model. The rule of third would have worked better in that picture (moving the camera angle to the left until her head reach the two third of the frame). Also when your subject is looking outside the frame, it often look nicer if the empty space is in the direction she is looking.
Don't hesitate to crouch down to her level, it's only fair that the photographer get herself dirty after she ask to her model to lay down in the dirt.
