This looks great. Although, you've put too much vectors on one side and that takes the attention away from Lightning and becomes the main focus of the sig.
But other than that, the sig looks great, and I like the little smudge/grungy thing you got going on the left side.
Lightning could just use a bit more blending in though.
:
my main issue is with the text
can't find anything to fit in with the rest of the sig...

i'm liking the background and i'm also liking the way he is blended in to the signature.. you did a very good job there

The effects are fantastic. I suppose my only critique would be the text, I would suggest not too have too many different fonts as it looks busy. The placement is perfect though. You're improving at a quick pace.
oh btw what the fonts i use for the top part of bothvthe zidanexgarent one and the ash and pickachu one 

might need to look at some tutorials I reckon..
!!!" I do like it, and I believe it is your best piece up to date. You got great text, the effects are nice, and just love everything about this piece.
