Oh so, what I wrote was right?

I was trying to refer to a picture that was drawn. I wanted to speak in third person about who made it. I am aware of работа and труд as words so far, but I wasn't sure which was better to use in this case. I guess I better start reading those grammar books I have now haha.
If we talf about pictures, работа is good, while труд is probably impossible.Работа Джошуа is anyway correct.
