Hello! NMM (Non Metalic Metal) Is something that is tough to learn! My own experience took me months and months of trial and error before coming to understand the basic concepts. Always eager to push and improve and some inspiration after reading the blog post from Surface fragments the goal to push my NMM was set! He writes about how the old masters achieved metallic surfaces . Specifically about how painted metals specifically golds that are successful tend to have closer value ranges as well as more limited pallets.
Gotta give a shout out to Segio Calvo Rubio for his fantastic instruction on NMM as well! Look out for his classes at Adepticon 2017!
Closing thoughts on the Brass. The final tone as well as the texture of the stippling is very nice. The contrast is pleasing as well. The final over all effect isn’t necessarily a perfect representation of brass as a metal. The light source could be refined as well over all though I’m very pleased!
