There is no agreed upon definition for what constitutes low, medium and high wrist. Some are higher, lower than others, but what is a high wrist to some is a medium to others, etc. I'd consider the bow pictured above a medium wrist. Some might even consider it low on a recurve. Just need to try different styles to see if there's one you like best.
I shoot mostly low, straight/flat wrist longbows, but have a few recurves that have what i consider medium wrists. Don't have any difficulty moving from one to the other. YMMD
