It looks safer. But just chopping it off so abruptly leaves a good sized void for the air to rush in and pull you back. I think if you tighten your taper before the rear axle a little bit you can bring all the surfaces much closer together, still within that framework, and keep enough air attached that you won't have nearly as big a void. It may seem like a compromise, but safety shouldn't be compromised. Good work and good luck!
