It looks pretty good. I like how you grayscaled some parts where the text is so the text stands out a little more. Good work!
I'm gonna tell the truthI don't like it =\ The colour scheme doesn't seem to work for me, it looks like you saw vomit and said that's the colour scheme I'll use! It seems like you haven't really done anything much to it at all, some blurring and colour changes, and that's about it.. Oh and Halo sigs are old and boring now anyway, also it's too big for my liking. Too tall. Anyway... With love, ~Rey ♥
The colors are a phail, sorry. Half greyscale, half color sigs are a no go. Tbh, I really don't see what else you did...blurred a few parts and that's it. The original looked better then the result...
