looking for some assistance before chucking a thread together properly!

Just bred what I believe is the first quad rosette with briar if there's others I didn't spot them via search, oop confirmed first with briar soft there's a quad w/ briar heavy! thought I was going mad xD
looking for a rough ballpark on value 👀👀

the gal

She's 4ros + 4bo, and has fully-bo eyes, skin, mane & shape, G3 overall.

Other quads I've seen in the 300-500gb range, but they obviously didn't have the new n' shiny briar, or traits to match, so not quite sure how to manage her ^^;
