This ship looks awesome! I like the engines a lot! They are super cool. You also did a great job with the accent colors. You made good intentional choices with where you used them. I'm not the biggest fan of the large turrets. They feel a little spindly to me, but maybe I'm just picky. That being said they are cool, however I don't feel like they go with the rest of the ship is all. The only other thing I would suggest improving on is the rear "wing" right in front of the engines. Those details on the wing seem bland compared to the rest of the ship. Without them I know that place would feel empty, but maybe replace them with some small detail that looked like they related to the engines in some way could be better.
Overall I really like the ship! Great work!
