I actually prefer the third one

... re-uploaded the 2nd and 3rd one. the X seems to fit more this time.

Well new 'X' definitely seems to fit more this time, but honestly that doesn't really looks like letter 'X' to me :p

If I saw this fist time I wouldn't be sure if that is some sign or letter 'X'.

I think the same way but its the font this way :/

The font of the first one is best I think, thought I liked the rest of it as the second one ;3
