Hey^^ I have a question regarding photo editing. A beginner photographer took a few photos of me during the convention and edited them in his style, which is...very dark and overuses shadows to the pont where my face looks...kind of disfigured...I kinda like the photos, but the editing is awful, so I took a shot at 'fixing' them...I'm no pro, so my edits look a little messy, I just did this to give you an idea of what I mean...
Trying to answer that fully.
The image you posted looks like it needs a boost in Saturation ( color ??? ). The background needs to be removed ( etc/dancing ants ) and some glam wouldn't hurt ( while I am against that ).
Going back into the image, more lighting to eliminate the dark-spots would have been great.
It appears that ( under exposed ) to hide the background as much a possible. A light source would not hurt at all.
If you did get your hands on anybodies image. It is okay to play around with it for fun but you shouldn't ( at all ) profit off it or call it your own ( in terms of portfolio pieces ). I mean collage is another story entirely but the individual edit would be there for fun. You could use it to show examples of editing work but not call it your own work, and not in a space where a person could see the original authors work. If the original author did request to remove the image you would have to or compensate.
Looking in detail through my image viewer. It looks like you cleaned up around the nose area. If there is light hitting the nape of the nose then there is light going into the nostril as well.
The sharpness of the image might use a jump as well, just to get that hardness. Otherwise a soft image is also prefered.
The entire background could replaced with forest. Just head down to a local park ( while it is fall ) and snap some pictures of areas with falling leaves and foliage. That is my opinion. A cast of blue wouldn't hurt and the horizon could go on forever.
