At the risk of sounding like a jerk, the final version of that sig could've been created in 7 layers, assuming the text and text effects are created with two separate layers, and the desaturation effects were created using a single layer. This takes into effect the gradient map and color balance layers, one each. Not meaning any offense, just saying 150 layers is a bit excessive for the result.
Looks good man. I think it'd be even better if you added a few spashes of texture in there, but it flows nice, the composition's good, and I like the colour.
150 layers layer spammer, hehehe joking of course bro.. its got a nice feel to it, and colors all work well together.
