Welcome to EPZ David.
Theres a few issues with this shot, though the pose is quite nice, as is the eye contact.
Its underexposed for her face; theres a distinct red tone to her skin. Underexposure may have been caused by the white dress reflecting light back to the camera and/or flash, and if so, applying a positive exposure compensation would help. If you look at the histogram, you can readily see its underexposed, - so get into the habit of doing this real time, and then adjusting and taking a second shot.
Its quite easy in photoshop to increase the exposure for her face and arms, and this also reduces somewhat the red cast. It also reduces the shadows around her eyes.
The colour cast may be due to white balance, so I have reduced red a little in a mod. Always shoot in RAW, especially weddings, so you can adjust WB in post processing, - ideally having used a gray card for calibration.
I think reducing the height by cropping a little space from the bottom, and adding canvas on the left would place her in a better composition in the frame, also done in the mods.
Ive loaded three mods. First is the original shot with the changes noted. next two have a degree of softening or diffusion applied which is often liked by the bride. All have been sharpened.
A tip for preparing an image for the web: read the guidelines in the site; first reduce you PPI to 72; then size the longest dimension to what the site allows; ensure that the method used for re sizing is set to Bi-Cubic; then "save as", using the compression slider to get close to the file size recommended, - a little larger is usually ok.
Then open the re sized file, and check its sharpness, if it has lost sharpness due to compression, sharpen as needed, and save again before uploading.
Finally, - read the rules for the critique gallery: let us know all you shot settings; your intent with the shot; any modifications you have made; and you have the option to mark any critique as constructive by clicking the named link, - however only do so if you do find the feedback constructive.
Hope this is helpful
