Um, yeah. Speed wise 10% of lightspeed is pretty fast inside The Limit, it's usually considered the highest attainable speed for a mere spacecraft (and spaceships are slower).
Outside The Limit (aka the Cochrane Limit or The Outer Limit), there's no particular problem breaking lightspeed so 0.75c becomes very slow. I really would suggest adjusting your numbers here.
0.075c would make you extremely fast for a ship - about five times as fast as the Saint Bernard which is probably the closest match in size to yours of the posted spaceships.
Other than that, the Starhawk looks good. If you need an origin story for acquiring it, then one of my avatar's little sidelines is selling decommissioned US military aircraft to Fen for modification.

You're only young once, but immaturity is forever.
