Don't ask for criticism if you can't implement or take it.
Anyway
I think the first does have good lighting, but I think you've overdone it and it looks complicated with the blur and the multiple lighting factors.
The second one has great flow, but negative space and simplifies the sig (unless that's what you wanted).
I personally don't like topaz, and I think it's a bit too much, maybe set the opacity down?
Good work on both.
