Hey long time no see man! These are much better than what you've previously posted. The renders cold be blended better. On the first one his left arm, our right looks erased. Same goes for the 2nd and third not as mch in the third. Dont like the text color in the first and 2nd. Looks good in the last two though. I'd lose the overlay border and just go with a 1 px black or a 1px color that suites the sig. They could use a little more depth as well. Overall looking good, hope to see more from you. :)
