Thanks guys.
CSM- I think the jagginess you're talking about in my sig is the way I glowed the white outline on the bottom render. I wished I raised the softness and lowered the width on the outline, but that's just me.
CSM- It's not really my style of sigs--but I like it!
pTuz- It looks kind of plain to me. Maybe try using a smaller width but a similar amount of height. I started with 500x150, now I think it looks bad on the type of sigs I make (render sigs w/ c4ds) and I like to mix it up, but my favorite is 350x150.
