It is a nice landscape, Gael, but it looks like a bit too much saturation. It barely shows in the sky, except for the slightly darker area along the top border, but the town and grasses / vegetation is quite blocked up. Saturation does more than intensify the colours. It covers up the detail, the more you apply. Possibly a slight amount of too much contrast as well, but it's hard to tell with the saturation.
It's really very minor amounts, but makes a significant difference.
People may flatter themselves just as much by thinking that their faults are always present to other people's minds, as if they believe that the world is always contemplating their individual charms and virtues.
-Elizabeth Gaskell
