The purple lighting could maybe be toned down a bit or on her just a little differently but I like it; I think that pop of color worked on the jacket and hair (less so hitting the jaw). The magenta jawline drew my eyes so made me notice her glasses are crooked, and once I saw that I noticed her bra looks crooked; it could be the way she's standing but it looks like she's holding the strap as well as holding the jacket causing it to pull a little to one side.
The subject was placed well in relation to the lights in the right side of the background, which add nice shape & color and visual texture there. The window lights to the left seem more visually distracting (especially that large window at street level).
I don't know if I would've noticed the bubble gum, but now that I look again I can see an almost circular line around the inside edge of the bubble.
Thanks for the feedback. Now that you mention it, I do realize a few things look a bit lopsided. But I think that's the way she's holding her head, and not the glasses being crooked. Definitely something to look out for with future models rocking shades, though.
As for the background, I'm glad it worked well for you. Especially considering it's a composite
The bubble gum is real, I can assure you. I did use Photoshop to make it larger, but it
is a practical effect. I think that line is just how the light refracted within the bubble, but I'm not totally sure.
Like vintagesnaps above, I don't like the lighting on her jaw, but it looks great everywhere else. It is believable as reflection of neon light. Other than that, I like it.
Thanks. That seems to be a common response here as far as the lighting on her face goes. I suppose it's a little distracting.
Here is a similar photo, with a few comments taken into consideration. I've desaturated the light on her face a little to make it less jarring, and did a couple of other minor edits. Different composition as well. And I've edited the OP to include this version:
Not sure which I like better, though.
