It doesn't look realistic, or at least in my opinion it doesn't look realistic. I'd suggest finding out what happens when a rose touches the ground. I think it rolls a little, but it doesn't just immediately stop when touching the floor. By the way, are you aware about the Last Rose taunt? Because it looks like your idea was stolen.
Also, for people who start discutions, PLEASE stop suggesting stats for things like Taunts, Cosmetics, etc. because only Weapons have stats!!! Unless it's a kill taunt (the only stat would be the instant kill), it has NO stats.
