This is one of the older signature I made before. It's Ezio from Assassin's Creed 2.
This kind of signature is called a "vertical signature" because of the fact that it's mainly length-wise not width-wise. These kinds of signatures are actually pretty simple, you just got to get a good render that is hopefully taller than it is wider and try to make the flow or the movement of the background to go from down to up or vice versa.
I'm planning to get back to updating this blog. Hopefully in the future, my plan shall be successful.
