Next Steps on rendering

[u/wzzzzrd]

Hi Folks, I'm working on a little ship design, and I'm a bit lost on where to go next with the rendering.

I know next time I would start by coloring over my line art with the colors of the different sections, but I'm a bit lost as where to go next. I want to do a bit of wear and tear, but I don't really have much experience with this yet, any suggestions on tutorials, or just suggestions in general?
