#6 and #7 the line under the word blog is unattractive. the font for both is too thick. we need something that looks modern, minimalist, yet vibrant and fresh. the letter 'i' in #6 is too big to resemble and 'i' in iBlog. the use of geometric design is fantastic and the colors are great but perhaps the colors need some effects like a glow or a shine but very minimally. perhaps a very slight 3D look with the use of shading might help.
