Thanks. I like the colors of the Gimp one best. But as for 'making' I think more ...umph went into the one with Inkscape. I like twisting and turning those gradients.
Plus there are some nice effects too. I like the 3D it can give.
The making of the things were completely different in each program. I had never done much selecting in Gimp and did learn a little more about doing that. In Inkscape I could take the 'thing' apart using paths and remove borders. Each was just fun do do. While I tried to get good colors, I found I was more interested in the doing part instead of color.
Here is one I just did in Gimp.
Probably enough of the mandala stuff. On to something else.
