Hah yeah, try not to cover your focal so much. It tends to ruin the render and the lighting.
The Fate Sig needs the lighting to be toned down and the render is sorta overblended. Other than that it looks neat. The top right corner has a "wavey" part, I would take that out, sorta ruins the depth (that or blur it more).
In the Mio sig, the lack of flow sorta hurts this one. All though it's not necessarily bad to have things all over the place, I think it's too much for that sig.
