Gonna grade these all the same since they follow the same format/style

ALL 4 SIGS: 7/10

My opinion when it comes to the grading but the sigs/cards themselves dont have much done to them. You havent added some render quality. You did add a border to make the cards, like everyone will be for the trading game. The jersey changes are nicely done (the Chara one is a bit off for the blue colours)
Just a pretty generic signature/card imo and so I am gonna give it this grade.

TOTAL: 700k x 4 = 2.8mil + 200k bonus (for making cards for the site = 3MIL
