Question: 

I'm thinking about painting the ceiling drywall with white semi-gloss. Will there be any issues with it? Will it look aesthetically pleasing or tacky? If not, will satin be fine then?

Answer:

While there is technically nothing wrong with painting a ceiling with a semi-glass sheen, you won't be happy with the way it looks.  Historically flat paint is used to paint ceilings because of its hiding properties.  Flat paint will hide any imperfections in the ceiling due to drywall finish problems and unevenness.  If you paint the ceiling with anything shinier than a flat or matte paint all the flaws will show themselves right away.
