Hey! I bought a bunch of photo references from drawing from Noah Bradley! But it turns out he's a nasty dude so here's a thread on some alternatives for references! (Please add your own, I don't have a huge library) Senshistock is a favourite! https://www.deviantart.com/senshistock
Were you interested in his landscape packs?? well guess what! There's a bunch here! and they're more useable imo https://photobash.org
Looking for something free? Well you got this whole pixabay website!! https://pixabay.com/
Unsplash is a very similar vein to Pixabay, free photos for reference or otherwise! https://unsplash.com/
https://www.deviantart.com/piratelotus-stock Is another model involved in a lot of stock photos! Their gallery is full of good ensemble shots especially!!
https://www.deviantart.com/jookpubstock Has a lot of really great clothing references and really great acting in their poses!
And don't underestimate the power of friends who get really enthusiastic when you give them a sword!
And don't forget 3d models!! http://www.posemaniacs.com/ is a place where if you can't find a stock photo that's /just right/ you can make it yourself!
Costume references? There's no poses on this website but this is probably one of the most accurate and specific resources on period clothing! Look at the CATEGORIES!! https://www.osfcostumerentals.org/OSF-Costume-Rentals
I pretty much ran out of resources (chaboi uses 3d models for reference more often than not), but PLEASE add your own!!
ADDING ONE MORE TO THE THREAD! @JennRavenna is selling reference packs at http://photoref.org/ and all profits are going to black charity organizations this month! The medieval armour pack is my favourite!
