Since the raindrops and my new coloured background would not work anymore and I thought they looked a little boring anyway, I added a gradient to all of them just to see how it would look like. I liked the idea of the slight colour change on their journey from the cloud to ground better than I thought and decided to keep it like that after I added a few minimal corrections. I made the upper ones fit the clouds colour and the bottom ones the waters colour.
Also, I worked on my trees. I wanted to give them details, like shades and change the colour of each one individually. Also, I wanted to turn the two trees I had into a forest, so I made more duplications.
