Sorry, no. That's an F/A-18C Hornet. A Harrier's wings are mounted behind its air intakes and its nose wheel is swept back. Also this jet has a carrier catapult attachment on its nose wheel, something a Harrier would never need.
Wish I could afford to commission you AND Vulpessentia. Your stuff is beyond amazing...I just started a new job yesterday, so hopefully I'll have some pennies left over after bills are paid this month.
