It looks like you through pikachu on a yellow canvas and added grunge brushes with different layer modes and opacity I see no effort in this signature



4th: I like the simplicity but its a bit too simple which makes it boring. The tilted render is a perfect way to add flow to the signature but you failed to do so and added grunge brushes which ruins the signature. The light source looks very awkward and the text is in a very bad spot, change it or remove it. This also lacks depth and is monotone and get rid of the border.

5th: Facepalm* Stop using grunge brushes they look horrible in signatures. This is very boring and empty and it looks like you tried to throw in a brush on the left side to spice it up but you just made it look worse. Links face should be more saturated so it can stand out more get rid of the text and border.


tl;dr

All of these signatures lack depth and proper lighting
Dont use grunge brushes they look horrible and amateur
All except the 1st one are boring and lacks a wow factor

Here's my quick tutorial on text placement
Draw this 3x3 grid on all of your signatures on a separate layer


These red circles is where your text should be


Examples



Probably the best CnC your going to get in this thread

renders in pikachu and mewtwo are pretty pixelly

pikachu's colour scheme is pretty annoying, bright yellow subject on bright yellow background, mix it up

pikachu, sarah and link all seem to be made in the exact same way. spammed with splatter brushes and the ripple filter or whatever.

and cant see bumblebee's gun, which should be a focal point(if not a secondary one)

mewtwo's background is pretty cool, the flow atleast works in it, theres a random white shape behind him, which is distracting cus i dont know what it is/dont like it etc.
also a few shadow lines of his hands in the top right hand corner.

at first glance, mewtwo and bumblebee are ok, paying a bit more attention to them brings up the blemishes.
rest are...

also, welcome back etc
