I'm tried last night to do some post processing to create a more trendy style or look. Here is my attempt below. What do you think of it? Any direction I should go with it, or any suggestions about post processing styles or techniques I might try? Any comment is welcome, good or bad.
I think you are overlooking an important principle in creating a trendy style or look. That important principle is that you must shoot a trendy style or look in the camera. That means you have to get the right pose, the right lighting and the right look in the camera. You can't come back after the fact and do it in post. Post can enhance a shot, but it won't make up for a poor pose, or inadequate lighting, or the wrong makeup, or whatever else is a problem in a shot. Work on first getting the style and look you want right in the camera and then you can "refine it" in post.
So where do you go with the present model, the outfit, the lighting, the background, etc? You might start with the background. As is, the lighting is uneven on the background and makes a lighter streak across the whole background. Why is that there? Can the lights be setup to get rid of that problem? So do that first. What are the model's strengths? Design the pose to enhance those strengths. Pick clothing that works for the model and make sure that clothing is properly fitted and draped on the subject. Pay particular attention to the way a model smiles. If they "over smile", then work for a more subtle approach that does not introduce excessive laugh lines. If you want to go for such an over smile, then use very soft lighting to minimize the problems of lines that are formed on the face from the over smile. Be sure the lighting is even on the model so as not to accentuate the negatives. Go for a lighting ratio that adds symmetry to the face. For some models that will be broad lighting and others short lighting. Be sure the colors are harmonious (red backgrounds don't go that well with blue jeans and a green top. So the above is food for thought.
