I really like the color combo, but i think that the front of the ship should be thicker and more detailed.

Excellent craft David! I love the overall balance. It looks really fast with those huge engines mounted. Placement of the forward and undercarriage weaponry is great.

I'm surprised nobody has commented on this yet. Very nice design. I like your color grouping, especially with the accented yellows. I also like your use of pieces to create the engines and coverings. Great piece of work.
