As far as figures, what we need is Dawnesis++: a revamped Dawn/Dusk/Luna morphing figure, with a midrange between Luna and Dawn/Dusk (let's call them Sonny/Sunny, as they'll need to be more distinctly boy/girl than Luna). Dawn & Dusk especially need significant resculpting (think Poser 5 Judy vs. Eternal Judy).

They also need good textures. The ones that they come with are, ahem, suboptimal (and I'm unable to justify buying any others for lack of useful/satisfactory preview images).

Don't get me wrong, they are great figures, but they honestly need a good bit of work to compete with Genesis. The good news is that they certainly seem capable of being brought to that point with a few months of work. The even better news is that they already take great advantage of Poser's advanced rigging techniques.

To summarize: Dawn and Dusk are built to last, but they need some improvements to gain wider acclaim among the Poser community, and they should be included as the default figures in Poser 11/Poser Pro 2016.
