This was a really good series until maybe chapter 30 or so around when Tatsu was trying to get funding for his movie. Post trying to get the grant from the anime studio, it feels like it abandoned all attempts at having Tatsu improve and instead basically stuck to having him draw and draw and draw. No introspection on why he was being constantly rejected, no comparing to the other winners on how he could improve, nothing. His friends helped him out, he magically got crowdfunded, he drew some more and the film just became successful. I have similar feelings about Nico's career too. She's now just a successful artist the end. Very disappointing. I wish it focused on either their careers or fleshed out their romance more and instead it did neither. Maybe around then's when the sales of the volumes and the abysmal numbers might have forced the author to consider that the manga would be axed.
I hope the mangaka finds more success with their next work.
