For what it's worth, this was a hard choice.
The first one has blending issues around the head of Batman.
The flow is weird which ruins the overall feel of the tag.
The second one has badly executed depth and some parts look unfinished (the smudge on the right).
The effects are all over the left side whereas right side seems kind of empty.
I'm also not sure about that text.
Would've posted more but it's really blurry on mobile, sorry if I missed anything.
