Good, very balanced color scheme. If you have time do some ice blue edge highlights on leading edges of the hull and turret and very light blue highlights on leading edges of the scythes (that used to mean something in the second edition and serve only decorative purpose now). you have some but they are insufficient for the purpose. Don't make then too thick. The best bay of doing it is to load your brush with paint then remove as much paint as you can and then using the side of the brush, not the tip, pull along the edge. Let it dry and repeat 1-2 times more to achieve desired intensity.
