You car looks good. I had a similar deal in 2012 … backyard job by a guy who painted professionally during the day. I was quite happy with the job he did. Something went wrong however and the paint on my hood started to bubble in just a few months. Over the next 10 years…small places the size of a piece of sand started showing up in several areas. My belief is that something (maybe moisture in the paint or primer) went wrong and a fix is going to require going down to bare metal. My current paint is still nice an shiny but there’s an issue at the primer level.
