i like the sig you are currently using more, but i think those tetris like blocks are really ugly, sorry but thats what i think.
You can try to be unique and original sure, but if the sig doesnt look good then you're at fault. I see good potential in all of your sigs but there are certain things that completely throw me >_>
on the first, it would be great if your typography was placed somewhere more ballanced, and get rid of those ugly blocks >_< sorry but they stand out too much and they are distracting, also i fail to see how it connects with the theme of the sig.
The second is my favourate of the 3, i just dont like the blending on the halflife 2 symbol, it doesnt blend nicely with the the highly contrasting font right next to it, it looks out of place, im not sure how you could fix it maybe making it white? or just not including it at all and removing that part of the signature all together.
the third is the worse, It has quite nice typography, but that leads to those nasty blocks again, they totally do not work with a font and image like that. There is a huge gap in the middle effecting the composition drastically, i have nothing to follow with my eyes untill i come to a harsh white line, it completely disrupts the flow, its like the end of the sig, if it cut of there and you added some nice stock it would look great, that stock is too contrasting and too disrupting to the composition there, it looks out of place and i wouldnt use it.
I know you might be getting angry with people, but they're only giving you their opinions, sure you may think its a case of anime stock on such and such a backgroud, which in some cases it is, but in other cases its a lot more work and a lot more thought than just that. I dont think you should bash other styles, not untill you completely understand your own.
