A brilliant and professional work. There is nothing 'easy' about properly drawing a shield bubble without it looking strange and you did a good job here!
FWIW (from a Trek nerd of long standing), those Andorian ships look like the old FASA tabletop game's Gorn ships. Still, that's easy to dance around. Old, surplus Gorn frigates that the pirates bought legitimately and then (illegally) re-armed.
