Liking the extra contrast. This version has much more volume. Well done!
Does feel like a different time of day and doesn't match the reference image, but those things don't matter. It's all about that volume.
So value studies are simple. Take an image, make it greyscale (use perceptual greyscaling if possible), and then copy it.
Don't use the colour picker and keep your images separate. Then just draw what you see in what brightness you see it. Limit yourself to
one hour or some similar size chunk you can easily manage.
The idea is to remove the confusion of hue and saturation from the mix and just focus on the values/brightness. IRL saturation and hue affect value, so perceptual greyscaling takes that into account.
Here is an album with all of my value studies using the fancy new BB code.

Sometimes they suck, and sometimes they are incomplete, and I didn't do mine every day because I'm naughty, but keep it up and you will become amazing. To help, post in
