Thank you! Power Source was chosen as a DD under my old account. It tends to be the favorite but I'm happy you like this one too. I always thought Poseidon's Puzzle had a Mer-quality to it, if that makes sense.
You know, now that I look at "Power Source" again ... a very faint memory of seeing it as a DD returned to me. I also changed accounts recently (been on dA for about 6 years though) - it really sucks to let go of the DDs. Still, it was a needed change.
