Okay, well here is what the tag lacks...Depth, lighting, flow, composition, blending.

The tag is pretty flat there is no real depth or lighting to give it any depth the composition is off and the colors are also a bad choice, the render doesn't blend well into the background or the effects, effects are boring and repetitive the text also ruins the piece for me a bit. Might I suggest reading a few of the tutorials around here they're all very nice and easy to follow along. as for the rating I give it a 2.5/10.
