Hi Caetano
I like the latest version for the hut shape, and the gnome, it feels very homely.
Other than that, I wonder if you haven’t lost your way a little?
These latest version feel a little like you are putting in stuff you think should be in there, rather than just creating an image.
In terms of pure value, I liked the very first image you put up. Since then you’ve added a brighter sky, a light background, brighter fog, now a glowing river. To me, none of these things have improved the image - but that is MY opinion, other opinions are available!
I wonder what would happen if you stripped everything back to the simplicity of the original sketch. You have spent a lot of time composing with your head, now forget all that and go back to composing from the heart.
Don’t be afraid of an image which is mostly darkness. Caravaggio was a master of this - keep the dark alive, but you don’t have to fill every space with something.
In the words of my art teacher …“It looks like you are trying to paint like somebody else”.
