I had to find a new way of making the clouds move so I used these tutorials to follow and utilise the existing systems to create clouds.
I was successful in building the clouds for the scene. They moved constantly when the game was in play mode. It was sad to have to get rid of the other clouds I made but now I at least know how to do them both.
I also felt there was a little bit too much empty space so using the landscaping techniques I had learnt previously, I sculpted the landscape in those particular areas. I then removed the tiles not being used which were covering the sea. I like that there are some more organic shapes in the level and not just blocks etc.
