While the image seems like it might coincidentally be in use in another logo, we like how all the pieces fit together in this treatment. The contrast betwee the larger font and the smaller might be too much but it is headed in the right direction.
Thank you for your comments and considering my design for your company. Although there are millions of different logos today, there are many similarities from one to another. You must consider color, stroke, type, etc. I will guarantee you that my designs are 100% original and if there is a logo like this one out there I would modify this to be your own.
Thanks OneStepGraphics #9 and #13 -- I really did use the word "coincidentally" with all seriousness and have no doubt about the origionality of you work! I appreciate the work you are putting into our nonprofit contest. This is an amazing process. What a great service!
