I signed up for the signiture school and my teacher is Icecikle. I made this sig with help of a tutorial, and Icecikle who helped me out when I needed help. This was the sig I created.
You cant even see the render. The right sides little twirls look like crap. It's very boring and low quality. The background is random. The border isn't solid. The left sides grey looks bad and random. No light source or flow. Look up some more tutorials, or maybe a new teacher. No offense to Ice.
