Well, Im going to toss my two cents from an amateur sig-maker.

Firstly, notice I said sig-maker and not Graphics artist. I dont view myself as a graphics artist, I view myself as someone who makes small works in photoshop and puts them on display for others to critique etc.

I do this all for fun. I have no desire to become a real graphics artist, nor to pave my own style. I make signatures the way I do, cookie-cutter and all, because a: its the only way Ive been taught, and I dont plan on forging my own path and b: because its fun.

I would try and come up with some abstract large art piece, if I found it fun. I find making signatures from renders, etc, what I already do, is fun enough and Im not too concerned about how unoriginal it is as long as I had fun making it and people who respect cookie-cutter sigs dont mind it. Its also something in my life that I strive to imnprove on, because theres nothing better right now, in my life, to motivate me to get better at it then making signatures.

Im done.
