Bulb Mode wrong aperture

Yesterday I tried myself at shooting fireworks , set up tripod , set to bulb mode and everything but i forgot to change the aperture so I Shot everything on f2.8 - the apertures were varying from 10 to 60 seconds (trial and error just to see what I can get since the film I used had some mishap shots anyways) now I’m wondering if the aperture is a big problem here , I used ultramax - how are the pictures going to turn out ? Super bright ? Super blurry ?
