A nice simple binding illusion, but I can clearly see the drawbacks it has for one to easily tell it is in illusion. First, the sudden disappearance of the person casting the illusion. No one just ups and vanishes without a trace. Second, would be the sudden burst of vines from the ground that begin wrapping around binding you in place and the sudden reappearance of the person who cast the illusion in one of the been pods attached to the vines. Now if one had shown using wood release or the ce plant release before doing this it would make the illusion so much more believable.
Honestly, too many flaws in this genjutsu for one to not know they are in an illusion. The sudden change of where you are now trapped in a giant flower bud? That just doesn't happen. A clear sign one has cast you in an illusion. Nothing really good about this gen as it can easily be seen as one and easily broken out of before it even has time to fully do what it is intended for, causing stress on the mind.
