My opinions bro
1st one is blurred, if thats a gaussian blur on the background of 1st, then tone it down a bit, focal points need working on, add lighting to focal points, and try to get a text that will compliment the sig, yours is just mucking it up right now.
2nd one same with text, blending is nicely done, defo the better of the two imo, but bring the render a layer forward.
