please give some comments, i might use it for my sig.
i have one more, it's totally different, but i can only attach 5 attachments at a time. so that will be for the next time
EDIT: the glowing things at the back are gone in some pics, normally there should be a gray glow at the back of every image
but some of them are actually look better without
maybe. but i don't know how i should crop them, i wanted to show only the X4, but it doesn't look clear.
here's another one, i think it looks ok, but i didn't spend a lot of time working on it. it's far from perfect though. lol
I think I like this one,

--But, what program did you use? Photoshop?
just like every other pics i've posted here: illustrator 
it seems to be your favourite program lately
well you seem to be very good at it.

yes, flash used to be my favourite program, but it's not really a drawing application, so i've tried illustrator, at the beginning it's really difficult, 'cause it has completely another system than flash.
but well, i've brought myself an excellent book and i've been watching lots of training video and now i'm pretty good at it

I like the second thumbnail attachment you posted. Recently I have been using nothing but photshop but I might try illustrator as those graphics came out pretty good.
it's not difficult though, it can be made with any program which has glowing effect and gradient fill, other than that, i just used existed fonts (beside that X)
EDIT: sorry, i thought you meant the other one. if you mean the red fire-like one, it could be made in photoshop aswell, i just hand-drawed (mouse-drawed) that using some kind of brush. then applying some kind of filter and a glowing effect (which come from photoshop).
they could be better, i think you are choosing the wrong matching colours
