I think pixelated is safer - because at least you can do your own coder art for the time being, get all the requirements in place, and then it's so much easier to convince an artist.
I mean, if you go for the detailed look, then you limit the number of enemies or items or furniture you can have - because it takes more time. A 16x16 animated sprite might take an hour or two - but a 128x128 animated sprite would take days in comparison.
I'd go for the pixelated low res look, do your best with the coder art, draw the swords and items etc as clearly as you can, draw the enemies as just single frames for the time being. Then if you go to an artist, you'll already have the content and they'll just have to go through it and replace it sprite by sprite - they'll appreciate that, having a distinct workload, having the assurance that the game is or will be finished. It'd be a lot easier to convince an artist to work for a percentage with that.

I got a fever, and the only prescription, is more memes.
