Realistic illustration of new flexible plastic package

Create a set of 3 realistic illustrations of a new type of flexible package. We will provide approved patent illustrations in .ai format (the top 3 illustrated in attached PDF). The output needs to resemble the attached PNG illustration in terms of realism, reflections on the package, 3-dimensionality etc. We will specify some simple liquid like ketchup or juice, not a lumpy one like yogurt. Other examples of the client's inventions can be seen on http://squeezystraw.com. However this is a different package with no straw extension on it. Freelancers interested in competing for this job must share one or more links to similar realistic illustration.
