hmm i like the first one, i just do not know what is going on in the right side. but not bad. the second one im not really feeling. seems to chaotic or something. good effects on the second ill give you that.
I actually like the 2nd one To me effects look sweet and colours too. The b/w one is a just a little empty on left side. Other than that they're both pretty decent tags. Good job ^_^
