Remember that this site is really active and a lot of the people who don't post on tags are other people who are learning how to make tags them self's :P.

Like Gaaf said, trying something new is always good.

Practice more with the pen-tool, make lines and try to make even tubes (lines near each other). The more you practice with your pen-tool the more details and the more designs that you can add to your piece instead of just make 6 circles and 2 zigzag lines. But remember, just because your current piece is too simple it doesn't mean that you should go hectic the next time you try a pen-tool tag.

Remember, simplicity with the right amount of detail is the best way to go about creating this sort of tags. With the right amount the tag will look nice and the lines won't be hidden.
