It's a shame the tag wall isn't full sized, but we can all tell that you got skills. ;P
Anyways, just general comments from me since most of the stuff has similar strengths and weaknesses and I don't have enough motivation to give CnC for like 12 tags... xP
I think you should try and make your pentooling/vectoring compliment your other tags a little more. Piece like 1 and 3 on the tag wall are good, but they feel a bit random, and compared to other vectored tags of similar style, they aren't quite at that standard. So, you have a choice, keep working on that style, and nail the polished and clean vector aesthetic, or use the pen tooling more as effects (4 and 8) rather than a focal necessarily.
Or you can just keep doing what you're doing, cause you are tearing it up. :D
