Pic 1: Amazing vector work, since the shades mix well with the background. I also like the first two fonts you used, however I didn't care much for the circles and the super thin font inside them. I think some storybook page looking squares would look nicer, and with the extra room it could allow you to use a bold version of that font
Pic 2: It looks realistic... I think that is a success.... I especially like how the legs look blurry, as if the shot glass has an opacity to it.
Pic 3: Beautiful black and white filter, and a perfect job avoiding the cat. (at least I think that is what you did) I really really really like the text and symbol, I think the lover text is also good, but the color is just a tiny bit off. Also, the website URL kinda blends in with the picture, and it should probably stand out a bit more.
Pic 4: Dr Pepper logo and text are in the perfect place, and the bottle and graphics are really cool looking... the only thing I can suggest might be making the logo and text a little bigger, to fill up more space and to intensify that line.
Pic 5: My favorite picture, I really can't think of a single thing wrong with this. Pretty girl, cool artsy background. cool text with a perfect color that matches the background, yet stays bold so you can read it. I love especially how the girl matches the bottles. Black hair and dress for the black bottle, White skin and background to match the other one, and rose heart and lipstick to match the red on both. This could easily be a poster.
Pic 6: Well, I really like the other one, so maybe I am comparing the two too much, but other than losing the color match-up, the product bottles look weird and blurry. The text looks really good still, and it still blends well with the graphics in the background. The girl being purple is catchy looking, but it looks like she has one arm since the white on the inside of the heart is preserved.
Pic 7: This picture looks pretty good, Without the purple it does have the color match-up, but the bottles still look odd. I like how you can see the fingers of the right hand and the girls dress through the heart in this picture.
Pic 8: This picture kinda creeps me out a little, since the vectored guy looks a little too realistic.
Pic 9: Very pretty spread. You did the color match-up again, and it looks nice. I like the fuzzy, space background that also shared the Red, Green, Brownish-black theme.
The font is nice and wavy. If the model wasn't doing a silly thing with her hands, and looking not so great in that makeup, I probably would like it more. The thing is, she looks silly, and that is gonna stop people from buying that makeup.
Pic 10: Ohmagosh so cute! *contains himself* Okay, well, I really like it, your color rendering skills, especially on the hair are pretty amazing, but I think you could have made the skin more vibrant somehow.
Pic 11: It looks just like a book I would find at the store, then not buy because it is from the author of Vampire Diaries. Good job though.
