You are attractively displaying the Adsense ads. I can't see how Google would have a problem with that.
yay ! the ads look good in that picture, and also it doesn't mislead user, I don't see any reason why google should have a problem with that.
Yes, it is absolutely all right as long as you do not violate TOS and I did not see in ur implementation anything against TOS .
MY advice is to e-mail the AdSense team and ask them. Some of the above reprezentations, strictly put an incentive nature in the middle.
