Welcome, Melissa! You are off to a great start with this one. Can't improve on the advice below, but still look forward to watching your portfolio through this project.
Nice sharpness and clarity. Creative use of less than photogenic task. As others have mentioned the lighting, I'm actually nearly ok with it. I might have gone with a tighter crop (off the top) but that is just a personal thing.
Best thing you can do with this, Ms. Nightclub Lady ;-), is somehow soften the shadows, either by diffusing or bouncing your flash. You want to avoid shadows with hard edges like the one at your nose and by your left cheek. They tend to make subjects look much harsher than they have to. There's a time to use such shadows though, to "break the rule" as it were, but I don't think that was the intention with this.
lol you really are getting into that brushing! you must have great teeth. :D Excellent job with the focus and the lighting. I'm still trying to figure that part out. :)
If I may ask a basic ? What kind of camera are you using? We might be able to share a few tips and tricks on how to soften that flash :) I noticed the stamp on the hand right off too. Funny how things jump out at you LOLOL Your focus is great though. Get those teeth girl!! :) I look forward to seeing more :)
haha, you look super determined to have clean teeth. The focus and clarity are good, but the harsh shadows aren't so great. On camera flash? I can't ever manage to get good lighting with mine.
Nice clear photo with good tones. Interesting pose, but the colors are great. Can't help wondering what the stamp on the back of your hand is from... Late night out??? ;-)
