Have the tape done? Using mesh tape of do you have the first coat of paper in mud?
I usually use paper so at this point it would actually be a second coat. I like to do one side of the corners, ie lefts and tops, and then depending on the size and type of mud either do the other side after the first side is done. After that move to the flats. Reason I don't like to do flats first is when you do the corners it's much more difficult in my opinion to get the corner looking good.
Don't use mesh in corners but if I did I'd want to do it similar to paper where the first coat of mud went on both sides and then repeat additional coats as above.
