Hi. I wanted to try something completely different for my concept. I figure since you can buy clipart puppies and kittens for a few bucks all day long at the stock art sites like istockphoto.com , I wanted to offer you something more along the lines of a real logo, that will look good in one color as well as full color. I think this concept will make an effective brand in all types of media, from single color laser printers to full color signage.
I'm glad you liked the version with the slogan on the top. I really prefer it there too because it helps balance the whole logo out in to about a 3:1 ratio. ( 3 parts across to one part down. A square or circular logo would be 1:1) The reason for that is you will save a ton of money on and large format printing you do, and you'll get a much larger product. Large format printers charge by the linear inch.
I did think my initial choice of colors were kind of dark, so I'm submitting a lighter version. Let me know what you think.
