The opacity of some colors may be a little better (had painted over some 2-3 times are numbers were still partially visible). These colors was therefore very scarce with the capacity. The brush in Gr. 2 is not necessarily geeinget for the smallest places, here the Gr.0 or 0.5 would be helpful (unfortunately not in the scope of delivery) The fixer was not quite enough, 5gr is something little. Despite everything, it was really fun, so try again it will.
