To be honest I think the amount you should charge should depend on what type of gfx it is, how many different things there are in the gfx that you have to add and pose, etc. So maybe somewhere around 5k robux/50 USD? Maybe more, or less depending on the gfx. A lot of smaller devs would probably not pay 5k though, but probably bigger devs and development teams.
To be honest, your gfx is amazing! I really love how you are consistent with the atmosphere based on the Game’s title. A little iffy on “The Lost Trails” of not brightness (lanterns too bright for me) but still well made.

I say if you are working with Bigger Development studio. Perhaps around $40+. But with smaller devs, I recommend <$15. Some small devs will pay small price even if its lower quality. It can help them get the job done based on their needs.
I charge around 250 per gfx but i cant find any clients that could pay 1K+ even though I know I work very hard on these gfx’s. I havent gotten the chance for any clients to pay me in USD.
