Fun fact, I had an actual picture editing class about a year ago, where I learnt to do especially recoloring of pictures, changing a background and building compositings out of several photos in a "professional way" (I passed with a straight A by the way ;D).
This helped me a lot creating
Day 20: Battlebacks 3
I have to admit, having 3 days of battlebacks that were "just" edits made me a bit nervous. They ate a lot of time and especially the recoloring to have them seamlessly match the floor tiles was not really easy, but it is difficult to tell how much people will like something.
So for example, here I had to get the right part of the Bigtree title, and then recolor it so it matches the grass battleback tiles to be matched with. I think this was an easier one:

This one was mostly cropping, but since the battlebacks for castles are very overloaded in MZ, i really felt we need something like this:

The following two were the mountain title. So, I thought...
One of the would be perfect for a battle on the cloud battleback ground, having clouds everywhere and just the peaks of the highest mountains showing:

And the other one for a battle on high mountains, matching one of the rocky grounds. If you compare them with each other or the original, you will see how much the colors had to be adjusted:

This one looks so innocent, but this needed some more editing than the rest. If you look at the original, "canyon", that thing has not only a flying ship but also a giant towet that are right in the clouds. After some swearing and editing, I hope none of you can see where they were without comparing the pictures ;3

This one was not that tricky to make, but tricky to see. It was actually part of Floating island, and due to perspective and the giant floating island it was not too easy to get a usable part. But I think, I managed it.
