#44 - a version of #34 with a different typeface and a border enclosing the type. #45 - another version on a circular shape. I think I prefer the angled oval as it is less static and there is a feeling of movement.
I like #47. Do they have those oval magnetic stickers in England that runners stick on the backs of their cars? They usually say 26.2 or such. I wonder if you made #47 a balanced oval it would lend itself to that application.
I like the idea. I still want the flames to only come from the top of the dog's head. The dog should be on fire.
#53 & #54 - versions with the oval straight instead of at an angle. I had a look at the stickers you mentioned and they are not the same proportion as these designs. They are narrower and I don't think these designs would work in a narrower oval shape.
I have had some god feedback from some friends and they really like your designs (as do I). My only concern is that the dog could not be separated from the entire image and stand on its own as an identifiable logo. Any way you can make the dog stand out a touch more and be able to be its own logo/brand.
The central oval with the dogs head and flames could be used a logo on its own without the words. Or do you want the dogs head on its own without the flames? Did you see the latest entries #63 & #64?
