possible tattoo sketch

A sketch I did earlier for a possible tattoo. I've been thinking about getting one for a while now, but have had a lot of doubts. Also, I refuse to have anyone else's art on my arm other than my own - so of course whatever I end up with will definitely be something I've created. However, I'm extremely critical...if by some chance I do like some piece I've done, it's rarely for longer than a week before I want to erase its existence and do something better. (I think it's a side effect of the brutal critiques I went through in art school. I have little attachment to anything I make.)

And if you know me, you know I have a peculiar fondness for octopi, which leads me to the above sketch. So far, I like it a lot more than any other sketches I've produced, so we'll see how I feel about it in a week or so.
