I didn't even notice that Barrels. xD
Anyways, this was ridiculously tough for me to choose. Both tags have weaknesses and strengths that mirror each other. Tag 1 is original as hell, but the execution somewhat lets it down. Not because it doesn't look like graffiti, it really is a great manipulation, but because the colours and quality are a bit let down. Meanwhile, the second tag, while not able to boast the same originality, is executed really well, and the final tag is pretty to look at. :3
So. I'm voting for Tag 2, mainly because it is the one that I feel, overall, looks better, and I'd be more likely to use. But yeah, it was really hard to choose, both great tags!
