Paras Hilton: I wish you hadn't said FINAL SUBMISSION! :( Your Poke looks watery, but not super shocky. I agree with an earlier post: changing the color of the lightning shaped elements removed some of the mental associations to electricity.
One really subtle thing you could do: Add a faint lightbulb filament to the lantern. Doesn't have to be prominent, just visibile if you look at it. Turning that lantern into a lightbulb would add some much needed electric elements to the design, but also help remove a bit of that supernatural vibe. As it is currently, it reminds me of a half-mermaid, half Legend of Zelda Poe Ghost. I do really like it, though.
Keishinkae: Your first design series is my favorite, but I feel like the current one is a definite evolution from that. Consider the Aligator Clip/clamp, as a possible way to make more of those electrical mental associations.
Aragornbird: Thunderprawn has been my favorite critter (fritter) since it first showed. For some reason, I imagined it floating in stormclouds instead of the sea or ocean, and I fell in love with the design. (I was prwn'd). The design wavered, but it definitely seems like it matches your original desing document. The antenna are throwing me off, though, since they remind me of Chinchou. Do you think a lightningbolt-style double kink, or making them sweep back (like a shrimp) would be too extreme a way to help differentiate them?
