finally the middle and right one are "dead". I an´t use them anymore :((( Crap. The left is still kinda new. I know the brush doesn´t look that "healthy" but it´s sable. I think ALL brsuhes based on natural fur/hair/whatever die faster than the synthetics.
a 10x6 cm part of the whole huge thing. I like it.. but I think you won´t have such a close look later when the rest is done as well. But finally I found out which colors work (while painting with colors that do not work... wonderful XD ). I think this gonna be nice.
