Its a nice signature, good use of colour, I love the yellow and blue together. All I'd change was the text in the upper right hand corner, you need to make that clearer, as its currently blurred.
i like the effects you have on this but i would take that tech brush out that you put in the top right corner, then you could see the text better. And with that pixel font put the anti-aliasing method to none(it's on the right side of the font size and has the abbreviation aa). it will be clearer and you could try it with a 1px black stroke.
It's good, nice colour choices and as Ne0b said, I think you should remove that tech brush in the top right corner.
By the way, it's over the 60k limit, i'd hate to have to remove a nice sig like that
