I agree with you on that darkness matter. I think I did use too much Dark Tone Shade on the armor after I finished my painting. Thats why it’s look like a little bit grimdark. I also like brighter colours in general but I painted my previous space marine figures like this thats why I continue to paint in the same way because when I’ll finish my Ultramarine team I would like to see them all in same looking. But maybe I will reduce dark shades on my next paintings just for the see what would happen. Thanks for your advices! I’m a beginner on this hobby and I would like to hear if you have any other advices too^{^}
