Tutorial Request

[Foppa]

I followed this great tutorial: http://www.gimpusers.com/tutorials/colo ... -gimp.html

But he never explained how to do the black curved part and especially the colored line that separates the image.

Can someone help me out? Would love to know how to do that.

Use paths to do the black part, do this on a new layer.
Then:
Select the black part
Make a new layer
Go to Select>grow>use 2-3px
Filll this with white and move below the black layer.
Then set the mode to overlay.
