I know what you mean the Miranda I retured took 2 weeks of 2 hours a day work plus a week end of about 14 hours to do it. I could have added more and more details but it came down to a point of will it work if released now or does it really need more work. Depending on the details texturing can take a long time to do, the more you add tthe longer it takes. Sad part is textures can make or break a model. I ok looking model with great textures still looks good, the best model in the world with bad textures still looks bad.
