I am not an expert, but I am not sure I agree with the MDF being a health hazard, I have quite a few plans recommending using MDF for various projects, and have not seen any warnings regarding health issues outside of the obvious precautions (use a mask when ANY dust is in the air, MDF, walnut, pine, cat, dog, etc) and build or buy a filter for the shop.
The scroll looks nice and a pattern I have not seen. Keep up the good work and enjoy the time.
