I have to say that I really do not agree with the attitude of being sloppy when your customer's paying less. It seems to make you unprofessional (no offense) when purpoted killing of vision and quality gets in the way.

I convince them to pay more beforehand, or size down my stuff (you want usable in high-res? Pay more please.). It's still high-quality and can easily beat the $10ers down the streets (partly because I don't make them using Poser :D) and they might even sell more!

If your work sells, you don't need to even approach these hard to please markets.

(I've done rather impressive stuff for my classmates for free. Spec job bloodsuckers.)
