Just made my signature..
First time with ps6 atleast, havent made a sig for years.

it's not bad if u remove the lens flare and maybe add a gradient map so it's less flat
also the effects look a little l/q but you could try blurring and/or sharpening them

Save it as a PNG or increase the JPEG quality.

no, never do this. you want to save all your signatures as .gif

it has the highest quality, allows for animation, and takes up the least amount of space in the internet. that is why internet is cheaper for users who optimize websites for .gif instead of .png
