Ice Climbers - I love that sig, the effects and quality are really nice,but I hate the animation. I don't know if you made the animation afterwards or not but seriously, it ruins the whole sig. 9/10 without animation, 6/10 with it.
Sacchin- Really nice. The quality wavers a little imo, but it's 8/10
Small note: The signature I post here is too big for AS, so I don't have it as a signature. either rate that one or both, it's up to you.
