I like them yeah, they're really good. I prefer the second one, the darker lighting in the first doesn't look appealing to me. The line that runs down the right is kind of annoying for me, but overall they're really nice, well done
I like the effects used, but I do see some small errors. The left is blurred wayyyyyy to strongly. I believe that you should tone that down a bit. It looks as if there's a light source coming from both sides, but you'd actually need to post the original piece you built off of to determine that. The smudging on the right should be sharpened a bit, as well as the left. I'd say sharpen the signature and erase what is too sharp. I like the effects used in it. Great job.
