If you love it, that's what matters, but I think it's missing something, like it needs to be filled in more, it doesn't look complete (IMHO). I also think the bead/pearl things look cheap, but that could just be the flash.
I think it's too monochromatic. The brooch bouquets I've seen have had some more color variation. The feathers or flowers (can't tell which it is) kinda look like hair to me.
Also the ones I've seen have a lot more brooches. Like almost entirely made of brooches. Will you post your inspo pic?
Eh I'm really not feeling the furry feather thing it has going on. My first thought was that it reminds me if some kind of fluffy dog with pins on it. Besides that I think it could use more brooches and agree with more color variation. Right now it's just kind of blah
Change the pearls they look like plastic beads to me or a children's necklace . I suggest getting a pearl inspired hair chain instead .. something like this and the combs could double as added broaches
IMO you need way more, theres too much dead space. I see what you were trying to go for but it looks so blah when you want it to be like wow. Also im not a fan of the strands of pearls hanging from the sides, I think it would look better if those were put on after you fill in the entire thing.
