Personal Logo

I'm working on my personal logo for the 3rd time in two years. It seems like I can do the graphic design thing for everyone except me!! I started playing around with it today and came up with something completely different than I had imagined. It has that nickelodeon feel to it, but I love the colors. Here are some of the versions that I came up with today:Can anyone give me some input on this? It's not as simple as I had originally planned, but I like the shape of it and the way the letters bleed off. The first one seemed a little boring to me so I added a few different elements to see how it would look. I like how the "pea" (yes, that green circle is supposed to be a pea) is coming off the "S" and bouncing in the 4th one, but I'm afraid it might be too busy. I have a clutter tendency. :) Also, I can't decide if I like the lines defining the "P" and the "N" on the outside or not so I added one on the bottom that doesn't have those little defining lines.

Overall, it's very different from the other logo's I've done for myself, but I can definately see some fun business cards, letterheads, and envelopes coming out of this. :)
