This two item I finished yesterday night, I make plum flower and branches. I use a con shape then duplicate them and group them together to make a flower shape, then color it with gradient. For making my own branches, I use path tool to create a line I want, after that stroke the line first, then go to filter > Distort > polat coordinates, and filter > Distort > whirls and pinch, I use this two option playing with them until you get what you want. This lesson I learn it from Gimp-Tutorials' Create a Surreal Piece of Art. Below photo is my result.
You can do it too, make your own today.
