Lots to think about. I'll definitely try some new things on the bottom, to see what I can get to stand out. I'm definitely interested in trying the weathering with some silver and black. I did just put in some accents in silver to make the unit pop more, and I'm very pleased with the result. I was trying to encompass the colors of this site into my ship, and that's where I'm having the trouble. I think I'm going to take out that light blue alltogether, as it makes it look too cartoony.
The issue with the guns is well taken. The little one on top is definitely out of place and needs to be replaced with something. Not sure what yet. I could move the bigger middle gun up there, but not sure how that's gonna look or function.
I have a couple more ideas yet, so we'll see how they come out...
