Good design, but I have several points:
First, the chirality (as shown in the pictures above) of the new Scorpion is incorrect. Please mirror the ship along its saggital axis to correct this.
Second, although the shape is excellent, more details should be added IMHO. I really like the detailiing on the engines; perhaps the rest of the ship could be detailed like that.
Third, the triangular gun points on the side could be made more like what you had on the Astaroth and the Aeshma, so they don't look like polygons tagged onto the hull.
Great job overall; FTW.
