Application review and appreciation topic + Lore Q&A

Hmm. In the interest of focusing my attention on getting one single race finished, I want to test the waters a bit, see what people are interested in. So, out of the following snippets, which one is worth fleshing out next?

Mi: Sentient Plant Fractals.

FLOR(OS): Intelligent bio-weapon intent on purging/controlling other sentience's.

(Undecided), Wekydo, Waki-No, Eecho, Bala-Ka, Muda-Mei-Ta: Extremely bloodthirsty voodoo snakes.

Tickers: Artificial clockwork (Regular clockwork, not the disease) collective, designed and run by the enigmatic Brass King.

Lumus (Post-ascension): Upside-down teardrop shaped psychics, not really interested in the universe. Looks down on any non-Lumus race, considering them to be "beneath their interest".

Lumus (Pre-ascension): Genocidal warlords determined to be the only remaining sentients. Not many left in the universe, after the ascension.
