It's alright, but comes across more as fan fiction than anything.
There have been many isekai stories which involve somebody being transported into the world of a book or video game (often as a side or villainous character), but usually it's a fictional book or video game. This story takes that premise but has it applied to the very well-known world of the Dragon Ball franchise, having the main character reincarnated as Yamcha. Like most isekai stories of this nature, fe uses feir knowledge about the source material to alter the course of events and prevent Yamcha from dying. But on top of that, it redraws scenes based on the original manga, which can create nostalgia in the readers. It is a bit weird how the protagonist seems excited about dating Bulma, but then prioritizes training over romance. The art does a pretty good job of replicating the Dragon Ball art style, but there are scenes and poses where it does feel a bit lesser.
