Gamera versus space babe

This is a faux comic cover I created for a re-imagining of pulp heroine 'Gerry Carlyle': an interplanetary big game alien hunter, who earned a living catching beasties for the London Interplanetary Zoo.
I thought it'd be cool to show her coming up against Japanese movie monster Gamera - the space-faring giant turtle.
The cover art shows Gamera grasping Gerry's spacecraft (which is actually a craft from the old 'UFO' television show.) Gerry, however, is ready for her counterattack: she's preparing to detonate her own space vessel... to knock out the space turtle!
