DONT EVER USE THAT FILTER AGAIN srs. It wreck all the flow the sig had.. You need to work on the blending. Lighting is good but you should limit it.
If you are going to use that effect don't let it stand out as much. Let it be an effect not the whole sig. Also, this signature needs way more depth. Blur and sharpen a bit more.
i dont really like the effects on this one. New style you're trying out? If it is then keep at it. Lighting is decent but the render needs to be blended a bit more as Donii pointed out.
