It's against PETA... hehe

Please read http://www.pxleyes.com/guidelines/photoshop/
5.6. 3D Renders or Illustrations as Source:
Using other people's 3D renders or illustrations (even with permission and no matter in which form they are offered) creates a false impression of your artwork. So 3D renders or illustrations can not be used as sources, unless they are entirely created by yourself. Only acceptable non-illustration brushes and clip art may be used, but you need to mention them as a source too. Don't use an image that has been altered by the source owner nor an entire work created by someone else.

CMYK46 is quite correct, you will have to replace source 1 and 3 with art that you created yourself. You should make the correction as soon as possible before the contest moderator sends you a warning.

Author, making the background (plaid) is pretty easy peasy, just draw one long thin rectangle and repeat the hell out of it spacing the apart. then merge the line pattern, repeat and then rotate 90 degrees and place on top with your choice of filter to create the Plaid. The sea turtle label can be made with a simple drawn shape with text. You have two days so it won't be that big of a stretch. Turtle Butter? EWWWW.. hehehe. hope you have time to fix this.. it's a neat idea

Author the link for the background is the download link. You should always use the link for the page that shows the image and the license/usage terms for that image. You did that for the jar and you should use this link for the background:

Remember the label must be entirely created by yourself and you have to add an SBS showing that you did that. You only have to show the original label you created not all of the steps.

WOW! Kudos for most excellent photo realism. Looks like an actual photograph for real! Old school photochopping. I love it!
LOL @ 48 % dolphin free. I just saw that. hehe

WOOT WOOT WOOT.. easy peasy fix and it is much better than before. Glad I waited to vote so I could give it a much better rating. Wonderful thinking all round

I agree with Drivenslush, looks much better with the new background!
