I'm using Staedtler Lumocolour & Staedtler Pigment Liner pens on 220gm paper.
The pigment liners are a new addition & a bit finer than the Lumocolours, hence the increase in detail.
I take my hat off to your work, too. I'm gonna try out some colour stuff later in the year & see what happens. I've got a bit of a list of pics to do, so let me clear the backlog first...
