I appreciate the invitation but your requirements do not match up to what you have provided. We cannot invent a photo of a child for your marketing piece for you. You need release from the from the person in the photo and also, none of the pics that you provided are conducive to creating the image that you are asking for. In addition, high resolution images would be needed as opposed to screenshots.

Dear Madam,

Is it ok, if i do it in A5 size?

WORKING ON IT SIR WILL SUBMIT THE DESIGN SOON SO WAIT FOR THE SUBMISSION

Message from the contest holder:

Multiple images are available on the Web for free and also for purchase. If
it is a photo that is appropriate for this project and it is available for
purchase then I am willing to do that. I have received numerous designs
already using free images as well as images indicating that I would have to
purchase it. The Photos of the bag have been downloaded using high
resolution photos instead of screenshots.

A5 is just fine.
Thanks!
