It seems so... Lack of interest I surmise due to the fact that of late photographers and models are flooding the site with mediocre snapshots and think that if you have a camera that makes you a photographer and if you can take you clothes off and stand or sit - that makes you a model.
I'm busy trying to keep my head above water while honing my craft.
Jene & I have been submitting images to galleries or juried competitions and marketing ourselves as fine art portrait photographers.
But I know if i need inspirations, there are still some of the best photographers/models here on MC
Sorry, the other MC (Model Coast) seems lonelier than here.
Unlike other sites, MuseCube has a lot more outreach. If you choose to do so, you can send people here who are not members, and they can view all your work. That's an option not available on most of the other sites.
For that very reason, I've gotten paid work off of MuseCube and Glamour Models, the only two open to the public. Why those two sites are relatively quiet these days is still mystifying, but they both offer more benefits than the popular ones, at least where I live.
