Curving out "Congrats!" in negative space

I occasionally have lunch alone doodling at my desk. Sometimes the idea I jotted down on a sheet of paper turns into my obsession and this is one of those cases. I tried to curve out the word, "Congrats!" in negative space. There's a lot to be fixed as I rushed to put it into shape but it was worth a shot.

Above is a doodle I made utilizing my lunchtime.
