JSX ST-7 Shinden,
seen here being checked by its pilot (another female character I'm drawing separately XD ).
At 6+ meter tall, size wise this mecha doesn't really compare to its bigger cousins, but it's more quick, agile and maneuverable, and is usually used in more specialized missions.
It has hardpoints on its arms, shoulders, and back to attach additional accessories and/or weapons. It also has additional manipulator arms just on the sides below the cockpit.
Operated by one pilot.
Anyway, I've put in some additional sketches. Hope you like!
