Hi Wendy. You got an original shot for the color challenge here, I don't have that kind of imagination! Is this all your lipstick?
You've set this one up well. Contrary to what has been commented below I think the white background works well. I don't think a black background would have brought those colors out as vividly as here. The DOF also works. I like the way the lips sticks dissolve into bluriness in the blackground, awesome effect. The colors are good, the composition also, you've left enough breathing space at the front :-)
The border is a bit exaggerated though. I think the red clashes too much with the image colors. I find a neutral color or black may have been better here. Also it is a little disturbing (for me anyway, but then again I always look for little small things, he he) that the lipsticks are not parallel and evenly distanced.
But overall, a very good image which I liked immediately.
Cool lipstick, do you actually use those, lol... Nice setup, well done, the only critique I would have would be with the choice of red for the line border, I think black would have worked better.
Oohh brand new and never been used. Too bad I'm too old to get away with using such colours ;-) The only thing I don't like is the glitter on the case. It's distracting. But you can't really do anything about that.
