Looking at your gallery I have no difficulty in finding detail even in your darkest pieces. There seems to be a comfortable amount of definition, I don't think it's an issue!

I went looking through a few and there seems to be no issues on my end. A few images that have heavy dark spots I'm still able to pick out the subtle details in them.

Could one of the monitors have a different contrast setting? There is also the possibility it could be the company that made them or one is going out. One of my monitors dose have a similar issue as what you are describing, colors in general are way darker despite it being at a high brightness compared to my other one, but it is refurbished while the other is new.

I can see all the details in your light and dark pieces no problem.

i have absolutely no issues with even your darkest pieces, i can see everything and tell whats going on

It seems fine to me, but I got good monitors for that reason. There's a lot of variance in calibrated monitors. You got a tough call to make for how much misslingend calibrations you want to prepare. Just imagine someone looking at your paintings on their phone out in the glaring sun in power saving mode. d:

i see clearly everything and i use a cheap dell laptop!

+1 to this but an acer! :D

I see no issues on my old laptop, either. at least I think the stark shadows are meant to be black, all other details are clearly visible.

They look good on my monitors

Checked on several devices, everything is good

There's strong contrast, but I see some shadow detail. I think it's compression in the files... try saving as Tiff files?

Seems very fine on my monitor.

No. Not that I could tell.

I've never had an issue viewing the darkened details of your work. Part of why I like your art, honestly.

I don't see any issues with the brightness or the shadows. The atmospheres of the artworks seem great and suitable to me.

No issues and I'm on a fully calibrated system. All 3 of my monitors have been done with a professional tool, and your works are easily visible on all three.

I can see the details on both my phone (S5) and monitor
