Sonikot, you have to know better photography first.
Direct bare pop-up flash on camera axis isn't that good, you can use it as a fill light sometimes but as a main light doesn't often do a good work.
It's more appreciable, in situation like this one, to go with available light; a fast lens and reasonably high iso do the work.
If you don't have a fast lens and good high-iso camera go with some tricks. Try to block the direct light with something, like paper hankie (open it up before, 2 layers is often enough) or a white business card placed to reflect the light up to the ceiling.
