The first one is poorly rendered (did you use the magic wand)
the colours dont work
no blending or lighting
im not liking the text
background kind of works
dont like the pinks lines on either side
good flow though (i look right at her
the second one the colours are alot better
same thing witht text (keep it simple)
lighitng should be on the other side (right top corner)
they dont really look like sig more like logos or a banner
hope ive helped
