I like that feel of it. Like a 8/10 It's cool, but plain. ^_^ That fan thing is cool though! Who's this hawt Eternal person? 10/10 for that one. No 12/10.
MP: First - 5/10 - Plain, and the basic flow is mucked up by the 'waves' in the line...Also, keeping the black stroke of the line doesn't look that good... >-< Second - 7.5/10 - I like the murky style, and the cyan highlights. The text is also well done, but like the first sig, the lines (especially the one on the right hand side) could do with some work.
7/10 - cool and good flow, but I think the render could be blended a bit more and more depth could be added.
9.5/10 the deadspace gets me just a little bit but otherwise its awesome 9/10 the ice looks really good, and for a signature focused on text its tight, but the spot above the text is really bare
