Definitely a little bit busy. Really great idea on the text and the placement of it as far as the smaller devin on top of the HESTER. That's a relaly great text trick getting the placement right. The washed out Chicgo combined with the bg makes it pretty busy though like you said. Also I am not a huge fan of the coloring in the sig either. Not sure why, but I guess blue just doesn't seem right for some reason.
I like it better without the Chicago in there. Not bad at all. The text kind of looks like the BG which is pretty cool, although it stands out a little too much. Also, there isn't much lighting in the sig. It will come with time though. I can see that your improving with every sig.
