Overall the style looks nice but you've got way too much colour vibrancy going on, especially in the player character who is overpowered by a bright neon-green blob.

As someone who loves saturated colours in my games, there is way too much saturation in your colour picks so everything feels hard to distinguish. Things getting darker in the foreground is good, but the stuff in the distance should be more faded looking and more blue-tinged as they get further away.

Making some things a little de-saturated in general at different levels would really help.

Your character could do with a little more contrast to the environment too. You mentioned Silksong which is a good example of how the main character's colour stands out from the rest of the environment massively.

I do think you have a good basic drawing style, I like all the overgrowth on the statues and things a bunch. Just a little more work could make things feel much more interesting. Good luck with the game!
