If this is a MOC, it belongs in the MOC Showcase (where I've moved it).
That being said... eh. Please don't take this the wrong way, but there's not a whole lot about this that isn't just swapped and tacked on. Outside of adding the lights and and changing the color, most of what was done was just parts swap. Where you did make a change, to the top turret, you just sort of tacked on a cannon and some green.
I think there's promise in the idea, and I like seeing different things fused together. But I'd look at how you can make the changes more organic with the model, so it doesn't look so stuck on.
If the above post didn't offend you, you're probably reading it wrong.
