Here I will try to show you what I meant when I said that I always try to make all my ships to scale as correctly as possible with each other. Please note that the Interdictor Heavy Cruiser that you will see below is totally not my design.
About this creation
Please also check my Revenge Class Heavy Carrier - Relentless to read further about the ship.
Before going any further please also check out the following video links to help better understand what I am trying to capture with this MoC. It will be clear to you the first time
What's cool about these, and I haven't figured out how yet, is that they look a lot bigger on the screen than they really are. I would suggest getting Gimp photo software, it's free by the way, and getting this fleet into orbit!
Making everything in scale is a real challenge, I know that. And your stuff even looks cool at the same time! You really have to photoshop (or something like that) the first pic, to let the ships float around in space! Good job!
