eek. Yes, you're right, the character does look better at 2x and is comfy within the given screen size. Beside the point one could make about mixed resolutions clashing, the tiles for your game world suffer from low-detail-at-high-res disease. I tend to think things look much better when the resolution matches the level of detail. I'm sure if you made your background half the size and resized it, things would look better. Less work, more appeal.
