Wow, I really like your work, especially these two:
The smudging and coloration in the first one is great, and the effects in the second one make it look really nice.
However, there's only one problem I have with your work - On certain tags, you seem to blur them a lot. I know it's to add depth and make the focal stand out, but on the two tags that monkeyandhead posted, it's taking it a bit too far. However, you seem to be kind of growing away from that, looking at your latest work, so it doesn't even really matter.
Overall, your work is fabulous. Keep it up!
