(adsbygoogle = window.adsbygoogle || []).push({}); Alright the most important part of sig making is depth, lighting, and blending. In most of my sigs i have a light source. I tend to put this on the brighter side of the render. If there is no brighter side you can easily make one with dodge/burn tool.

Also the background plays an important role for the outcome of your signature. You want the background to blend well with the render you use, for example you can grab your render and smudge it to your liking so it blends perfectly with your signature. You also don't want your background to be too bright so people notice your render when they first look at your tag; as your render should be your focal point.

The size of your sig is also something than can help. You don't want it to be really big so it looks bad(some cases it can be used big and still look fine). I like to use a size of a height in the high 300's or early 400's and a width somewhere around the early 300's. If you don't like that size you can always choose differently and find what is comfortable with you.

Also you want to start off by looking at some tutorials, its not ripping its just guidance. Another key thing is taking your time. You can't expect your tags to be finished in 15 minutes, if it requires going an extra mile to get to perfection or something near it, then take your time and walk that extra mile. Also have fun with your signatures sit infront of your computer staring at your render and try to imagine what would make it perfect, what would complement it.
