I'm going to grade the first one..
Effort: 2/2 sure
Looks: 2.5/3 I'll be nice and give you the 2.5... I agree with IR's grainy comments, it's also way too plain. Doesn't seem like much work has been done here to be honest. Try and make sure the render touches the top and bottom of the sig
Creativity: 1/1 sure
final: 6
