Entry #1...I really do like this a lot! The colors are perfect, and I like the emphasis on the last name. My only two things, is the the PB looks a little bit like a heart, which I don't know about..but I like the way it looks so I'm torn...and the slogan is maybe a smidgen to small. I like the slogan small and the emphasis on the name, but the slogan may be un-readable when used on a business card or email signature.
adjusted the b. I think that solves the "heart" concern, though it would be nice to have it there too as a hidden element to symbolize your passion for your work. The slogan was also adjusted to make it readable.
