Here are pictures with both the top wing panels in place. Both sides now have added grill tiles.

Same idea on the other side:
This is the begining of the top center panel. This piece will hold the second half of my modified section that will cover up the gaping hole in the front center of the ship. I won't be able to finish this part until some more parts arrive but enough of it will be done to be able to put it on the model.
At this point I'm waiting on black pins with bushings and black 1 x 1 modified tile clips. The dark red ones look good, but the black / dark blue combo looks better so I'm going to try to replace all the red/ dark red parts except for the engine tiles, which still look cool.
