Thanks for feedback, Swaggersaurus! One star yields 11.5/25 points? Is that a logarithmic scale?
You too, Novaray. I guess my intention was tweaking the existing designs, not redesigning them. I didn't want to stray too far from the original concept. Expect the same to go for my entries in any later rounds.
Also, in hindsight I should probably have made one Vanilluxe version with two female heads and another with two male. Would be less confusing.
