Oh man oh man. I was expecting a simple rehash of Ruro's and Slaves designs, but I suddenly feel like a kid in a candy store.
1. A labcoat is tempting, since I'm a proud physics major, but armor can be pretty cool too... I'll leave it up to you.
2. Hm, Caduceus or Asklepian? I think I'll take just one snake.
3. Neither the scope nor the hat seem too necessary to me. Add either if you feel like it'd look good.
4. My instinct is to say Monocle, but could you make it like a high-tech monocle-ish thingie? I love the way you draw machinery.
5. Whip, I think. Maybe whip-sword, like Ivy from Soul Calibur?
6. Tentatively, a full bodysuit. I dunno. Tights have never really been my thing. It's your call.
7. I'll take the coat. Coats are good.
8. Eight snake tails could be cool, I suppose. I could go either way, though.
9. Hm... No preference.
10. A mouth full of fangs would be best, I think. One fang would just make me cute. :<
11. Ribbons + Scarf, please. :3
No need to include all of these things, of course. It might look a little bit busy if you were to do so. Also, the closer it looks to the existing designs, the happier I'll probably be. I'll put my trust in your aesthetic sense, though.
