I'm using the Dragon theme, at least for now.
I'm using Dragon currently mainly because I usually log on at night
and the Dark Colours just suit me for some reason, it just suits me,
and it blends with the night and the Phoenix,
although it's a cool design, it's just to bright for me.
I might use Phoenix when I'm on at daytime.
I think it would be cooler if all four Divine Heavenly Beasts
(that means the Tiger and the Snake Tortoise) were included as other alternate themes.
