I like the idea/scene.

This is a nice style, somewhat painterly with a dash of cartoonish. I can definately see a game in this style. Those tree trunks however are just begging for some AA. Thanks for sharing.

Love the scene I could see it for a game 

Thank you, I have updated the images now. :)

You don't need to post a pre-zoomed image unless the artwork is meant to only be seen at that size. PJ has its own zoom buttons, and pre-zooming makes it harder to see your image at more intermediate zooms (e.g. a 5x pre-zoomed image can be seen at 5x, 10x, 15x, etc, but not at 6x or 8x).

For preview images, it's best to crop instead of downscaling. Downscaling makes a mess and isn't strictly pixel art because the computer's placing the pixels for you.
