What markers and pencils are you using? I love layering markers under pencils! Crayola super tips faber castell Pitt pens and tombow are my faves for basing especially on double sided paper.
Oh yes i love all those too, i only have like 6 pit pens but id like to collect more in the future ! I based these trees with the Arteza everblend h20 ultra ! I got them at Ross one time, i showed them in a previous coloring update too !
