I haven't made a signature for a while - well I made on for Regnenth but I haven't made one with a render/stock that I chose for myself, as I can never think of what to do.
So here's one I made:
v1

v2 (added glow, smoothed off the render's edges)

v3 (smoothed off bits missed around hand, got rid of the blue and added some colours from his jacket)

I couldn't find anything to fill the bottom left corner and it's not really a special signature in any way. Just wondering what you guys thought of it and what I can do to improve it.
