Hi Jan, thank you for your comment!
Yes, I myself was also thinking about the necessity of this "grass-tuft" when I cleaned up the figure.
Finally I left it, having the earlier experience that: one can remove a part later as well - BUT to recreate a cut off part once again is much more difficult.
Also even in the course of painting I found it not too realistic to have a green grass on the desert surface.
I shall remove it!!
Best regards-
Sandor
