Here is my workflow steps that I'm sure that most of my fellow PS users follow:
1. Skin Fix-Edit the most noticeable looks such as blemishes, acne, moles and sun spots. Remember to keep the noticeable moles that parents look for or they'll wonder why you removed the most obvious birthmarks. After removing the most noticeable skin flaws, I use a light airbrush to smooth the skin.
2. Garment and accessories fix- Any obvious wrinkles I fix. From the photo above, I didn't like the way Brittany's dress poofed in the skirt skirt so I adjusted the skirt my way to a cleaner look. I also fixed her sunglasses without the reflection from my strobe.
3. Overall look fix- I added major vignetting here and composited a stock photo into this photo to give a cooler artsy look.
4. Stop and take a break and come back to my photo to get a different perspective. Sometimes walking away from my editing can give me a different opinion.
4. Sharpen photo.
