Fighting the sun portrait newb

Less than ideal time and location to shoot but am sure my inexperience didn't help in managing the contrast. Welcome CC and insights to better manage these situations. Got subject under an umbrella and a nylon scrim held by assistant (i.e., the wife) and had a speedlight camera right (under powered in hind sight). Need to get this closer in camera and rely on less on post.

skin tones/color look good, maybe turn down the saturation on that greenery

its super pixelated. was this shot OOF and sharpened? why does it look so pixelated?

Using a scrim (or shade) can be useful to get your exposure values down where you can use fill flash effectively and not have hard shadows on the subject, but if you have a sun drenched background you have this problem. Its compounded when the she shadow from the scrim is so small the entire back scene is overly bright. The best bet is to control the ambient if you can by stopping down a bit (lowering ISO) and increasing shutter speed if you can do any of those things.

I'm unable to explain the pixelated look you're getting. Here is section of zoomed raw image saved at the 150KB POTN limit. Curious if others seeing same. Thanks for reviewing and comments.

Thanks for putting this up. Its because it OOF and appears to have been sharpened. When OOF gets sharpened it pixelates.

If you have a white bounce reflector, you might try lying it in the grass in front of her just out of camera range. Might soften the shadows under her chin and open up the eye shadows a bit.
