This may be my first freelancer work also, although i am in poster designing for years. I can make the poster you ask for, and as i have this in my mind from the first reading, there can be the products colourful and shining, something like alive beings, but not comic/ children style, but with a total image of "earth connection". You may also tell me more information about your store, what's its colour or how you want it to be. Any information helps so it is more close to your shop image. Would be happy to cooperate with you, and start our virtual experience of business...
