Don't discount those two items. Both are extremely important.
The editing is what I was really looking for. Worth shelling out a cut of royalties for me at this point. Art, not so big a deal for me. I've got a pet, professional artist who can't say "no," as she's family. I was originally going to just hit Smashwords for my novellas until I stumbled across a Urania submission call and figured I'd give that a go.
Editing though... that's a good chance for me to get some Powerful Enlearnment. It's something I'd be willing to cheerfully split royalties to get as I can't exactly afford to hire a freelancer. I've got some good beta-monkeys, but could really use a content editor who's not already immersed in my story-verse's other stuff. And to be honest, I know I've got a lot to learn; a Right & Proper editing would be a great learning tool. (Not to be cocky, I
know I've got a pretty damn good voice and world-building skillz. I just started submitting things this year and except from Clarkesworld, I typically get personal rejections from pro-markets for my shorts. Usually raving about my Voice & world, but saying "It felt like part of a novel," or words to that effect. (Yeah, those short, crisp stories just aren't my strong suite.) Plus, my betas read for a couple of Big Damn Pro Authors and I trust them to not blow smoke up my hindness... but flow, pace, continuity and such I'm not so sure about.)
No idea what's happening with that project though, not much in the way of updates and no answer to the query I sent a few weeks ago. Started doing character sketches to bounce over to my sibbie so I can self-publish if the story gets rejected or I just decide the project's gone off the rails. I hope that's not the case, because I like the idea behind Musa and thought they might be a good fit, although the horror stories are making me wonder if a rejection would be a good thing.
I'm willing to see what happens with the novella currently their hands and B) how things go if that moves forward. If a novella falls on it's face I'm not really taking any major damage... I've got another novella or two I'm tweaking, and the 1st book in the main story arc only has a few thousand worlds left.
