I don't normally do sigs, especially this type, but I gave it a go. (I was going for depth) Something feels missing.. Stock: Spoiler
Last time I tried putting effects on a depth sig, my eyes were all over the sig, not the focal. I'll try but I don't think it'll look too good.
Well Depth pretty much blows anyways. And you can execute efx without making a split focal. And yes, efx do help with depth.
