size dosent matter one bit, its composition that drives a piece of art, i like v.1 the rounded corners works well with subject , size and overall composition.
1/ Art? It's a sig. 2/ Size is directly related to the composition of a piece, if we're going to use a standard box method then the size of the tag will affect where the light source should theoretically be placed, where the focal is and where the negative space is. All of it changing relative to the size etc. of the tag. I do agree with the first poster, size bugs me a bit. And size can affect somethings aesthetics. Aside from that, 'tis hawt.
