Fourth Photo, Editing Steps

The steps:

1. First, I used the levels to make it brighter.
2. Then, I tinted the whole picture orange/brown to make the purple flowers look pink.
3. I tinted it again with dark brown.
4. I used the "curves" to make it brighter on the whole, but darker to bring out the shadows
5. Lastly, I desaturated most of the yellow, increased saturation on the red, and desaturated the whole thing a little.
6. Done!
