I have felt this way for a while now . I'm no longer hurrying to finish a build , instead I enjoy working on the subassemblies . It can be the rear suspension or the engine or even the engine bay and I might spend a month or better on just one area !
Even though my detailing is a long way from some of the stuff I've seen on this forum , I enjoy the challenge of trying something new with each build .
I guess that's why it takes me forever to complete a model !
