they all have work to do none of the bgs match with the render at all
the txts for each one r also bad
for the second one and 3rd one the bgs r going over ur render its more noticeable on the 2nd one
none of the renders blend into ur sig
looks like there was not to much work put into it(it looks like u put a bg then ur render then txt)
i give them all a 2/5 cuz i know ur a beginner but look at some tuts to get better
