Alien mascot/logo needed for smoke shop

I am needing a mascot/logo made for my smoke shop "Area 420" I am wanting something that is unique, friendly looking, and remember-able like the alien from the movie "Paul" and the alien from TV show "American Dad". I need the image to be very large with a high DPI setting. The image must be editable, re-sizable, and have a transparent background. I am looking to having the alien look stoned and relaxing shorta like the frog picture I attached to this post. I am asking that you create a sample of the mascot protected with your watermark and the person whs design I like best, I'll contact for payment and further work.
