Help Me Choose Images

I just got an email from IStockPhoto telling me I have a couple of credits which are about to expire. I don't know about you, but I hate to waste money I've already spent, so I thought I'd pick up an image or two for future use. 

I'm currently working on the second book in my Phoenix, Ltd. bodyguard series, tentatively entitled BOILING POINT. I've thrown together several possible combinations of images that I think might work for the cover and would appreciate your opinion. Since this will be the second in a series, some continuity might not be a bad idea. Here's the cover of UNWRITTEN RULES (Book 1) to refresh your memory.

I'm considering three background images: a Chicago cityscape, smoke on black, and steam on blue. The cityscape relates to the background of UNWRITTEN RULES, but the other two express the BOILING POINT title (this heroine goes undercover as a personal chef). Both figure images features legs like UNWRITTEN RULES, but one is more prominent. The other is wearing a red dress, also a tie-in with UNWRITTEN RULES. The title will be in the same font, but could be red or white.

Please let me know which elements you think make the most striking cover, individually and/or together. Also, please feel free to tell me to keep looking. I really appreciate your input!

Help Choose My New Book Cover

Five months ago, when I began this journey of self-discovery I call my Second Half, I crafted a plan for a new life to include writing, book cover design, and editing. Now that OG and I have The Big Move behind us, I've started to focus on my other goals for the year. In addition to creating covers for other authors, I hope to self-publish two books--one full-length novel and a Christmas novella. I love my current publisher, but I'm excited to branch out and one of the main attractions of self-publishing is the opportunity to do my own covers. 

I'm well on my way through revisions on my first contemporary romance, Unwritten Rules, so it's time to start experimenting with cover designs. I've put together three preliminary mock-ups and am looking for your feedback. 

Based on the blurb (below), which cover best embodies the tone and content of the story? Which would make you want to buy the book? (If nothing would make you want to buy this book, now would be a good time to mention that, too!)
Do you like the colors and images?
Do you prefer to see characters on book covers or just settings?
If you like figures, do you prefer to see their faces or just bodies?
Which fonts do you like best?

I'd really appreciate any input you might have!

Here's the blurb:

Things aren’t going Madelyn Li’s way. Her bodyguard agency is teetering on the brink of bankruptcy, her grandmother keeps hatching plots to marry her off, and someone is trying to kill her latest client. All she wants is to safely escort thriller writer and former CIA agent Carter Devlin on his cross country book tour and collect her check, but two obstacles stand in her way: a shadowy assailant and her own growing attraction to her dashing client.

Carter Devlin has agreed to accept the beautiful and determined Ms. Li as a bodyguard primarily to appease his publisher. After all, who would want to kill a beat-up, retired ex-spy on a book tour? But when the attacks turn deadly, he soon learns there’s more to Madelyn than a pretty face and tempting body. Will the spark become a flame before a killer snuffs it out?
