I don't know about other people but I personally hate when people use clipping masks and add it to the side of the sig. It looks like you're just trying to fill in space. but the sig itself looks nice...
Im not a fan of the block on the side, plus its way overused, also not too keen on the lines around the text, they stand out too much imo. It is your best so far though imo
not digging the applied image on the left and the text is alright nothing to complain about but take those things around the text away well anyways it is your best 4/5
