If there is anything to be said against this, it would be color control. I assume that you are using as many pieces that you can get ahold of, so I understand why your color usage is hodge podge. That being said, you have some advanced and innovative parts usage. For example: the radar dish. Instead of just having one dish shaped thing, you have a complex dish with details. Also, you use slope pieces to detract from the boxiness of the turbolasers. And, your control station is round with wrap around control panels. All together it shows that you are attempting interesting parts usage, and trying to add some dynamic complexity to your MOC. Good job on that. As for color control, all I could suggest there is build within your parts availability, and work your way up toward something this big.

Thank you
