It's not yonsun-nobi, yonsun-nobi is not style, it's length and that length is 233cm, not 190. It's like "I made 92-inches-bow 75 inches long".
No one even sell arrows less than 85cm, children who should use shorter arrows are not strong enough to draw even 7kg bow.
Bow base(distance between bow and string) is 3" on the photo, which is twice small than any real yumi.
And draw is wrong, both hands. Hands should be strictly in the same plane as body, string should be far behind ear, left wrist shouldn't be so crooked.
