i'd like to apologize for keeping your ask in my inbox for so long. truthfully, it's been some time since i've drawn, but i've kept your message throughout the years in my inbox to inspire & remind me to come back again soon. thank you for appreciating my dnd work especially! it's the type of work that i relate closest to, and i'm happy to know that is resonates with others as much as other work i've shared. it means the world!
for my current process, i use procreate + rusty nib brush packs for all my digital illustrations - but in the past, i used photoshop + kyle webster dry brushes! for color, i use any sort of textured watercolor wash (brush or image overlay) on a rendering mode over my flat colors to make them more dimensional! i often use the same brush i sketch with to line my work as well; pencil or bristle brushes tend to have more variety in texture, width, and opacity that add a lot of dimension to lines than a usual harder edged ink liner. lastly, i tend to duplicate the lineart after its finished, change the color to something like a saturated pink or teal, and set that cloned layer on a rendering mode like 'pin light' to make the whole thing "glow" - fun way to also add dimension!
