I agree. For the most part, a fine effort and result.
If these are people you know and you have a photo of the lady with the bad right side of her face, use that to help you rebuild her nose and her eye; probably the cheekbone too. It's the nose and eye that stand out immediately.
The bottom of the photo needs creative imagination to pull into shape as the original doesn't give you much. The increased contrast/levels will help you see the detail. Also the dress, especially on the right has an ill-defined border. One thing you can try is making a layer above and adding some of your own shadow lines. The contrast will help there too of course.
Keep up the good work.
BTW, to get rid of extra attachments, which happen once you've uploaded an image and re-upload just deleting on simple edit, go to edit, then down at the bottom choose advanced. Scroll down till you see manage attachments. It will show you all your recent images and the 3 for this post will be in the lower window. Choose the picture to delete, click the upper right hand corner (checkbox or "X" I can't remember) and delete. Then just X out the whole window and save your edit.
