i posted a thread of these on twitter quite a while ago but i only just realized i never posted to tumblr- so here you go!
in this google drive folder you will find reference sheets like the one above for most of the characters in dgs, including wagahai and toby! it should be spoiler free unless you open the spoiler folder.
i also have a folder of all of the character models i have ripped from the game so that anyone can open them in blender! i even have the model for the old bailey in there in case you need a reference for it! (some of the models are old uploads and not all of the meshes are properly named/textured, i am in the process of going through and fixing them up)
all of that said, i have not ripped every single model from the game, so if you have any requests for models/ref sheets that i haven't made yet, please let me know by DMing me either here on tumblr or on discord @/alaskanbullworm- you can also send me an ask about it. (if you want to request via discord, please send a friend request and then a message letting me know that you're there for a model request- otherwise i will probably assume it's spam and ignore it lol) unfortunately i am currently unable to rip the dlc costume models, as much as i wish i could.
anyway, i hope these are helpful! :D
UPDATE: i have found a way to use more color-accurate textures for the models- i probably won't remake all of the ref sheets but if you want to colorpick from the character models, i recommend doing it from the updated textures i am currently adding to the google folder!
