Hey Layton,
didn't have enough time right now to work on it.....will try later.....but a highlight recovery..........using shadow/highlights (one option) may bring some of the clouds back into range. You may also want to do a multiplied layer on just the sky.......to darken it and bring out details further. This would address the sky issue Kaushik mentions. Nice and sharp from an airboat.......and the moss hanging down from the trees acts as a nice framing element.
Nice work getting a good composition from a moving boat Layton. Select the sky and reduce it using a curves adjustment - that will add additional drama to the image. This is what Roman is suggesting.
