What does it mean "it's not coming together" in this context?
Agustin is artist. he's putting his pictures on the show
but he decided to pull out of it by saying this line.

"I hate this, but it's just not...it's not coming together.
So I'm gonna have to bow out of the show."

What does it mean "it's not coming together" in this context?
It means Agustin isn't satisfied with his work?

Thanks in advance for your help :)

Answer

Agustin is saying--- that the work he is doing , is not going to the direction he wanted it to be. For him what he is doing in the show, is not satisfactory in his taste or feel. The feeling of doing something that is not satisfying or being cohesively going well. The art of putting things together completely  requires a degree of personal satisfaction. An incomplete work is not satisfying.
