So when I got home yesterday, I felt really tired. I did the panel lines with a Micron pen again and hit the whole thing with Floquil Dullcote. Still partially shiny, but this is how it'll stay because I like it this way. I do respect all of your opinions, but I am the ruling authority here!
It won't be seen in extreme daylight situations like this, nor too up-close with model-builder types. It'll probably sit on my diorama at next year's school art festival.
