Most of these topics require a wide information about them to draw. For example detox or medical weight lose, I dont know how to draw them. Internet does not give us enough information or pictures to imagine something. And I dont think people draw lots of logos for that prize and due to low winning risk.
Maybe you should open a job in icon design, or give us a wide information to draw them.
Thanks.

Hi

I was wondering exactly how big do you need the packaging logos to be?

Hi

I saw that you cave me a rating, if you could tell me what I could do to improve the designs that would help a lot.
