@jimnakos It's mixed here: half is totally from imagination, another half while watching anatomy content (sometime copying, sometime improving a new view angle). Same for clothes, sometime trying to imitate a random photo, sometime trying to exagerate. I try also to redo the exercice while traveling where I can't access the reference so I can solidify the memory.

@Blort Haha, yes, I tried to keep a single page on my sketchbook to try random pen. I adopted a cyan and pink ballpen this way, but I kept my Bic ballpenpoint orange thin 😆

@Splig Hey, thanks. It's difficult to directly go on paper with a ballpoint pen. It feels like I'm less at half the skill I can do on computer, or with solid pencil fondation guidelines. But if you look closely I often use a white correction pen (especially when a line really waste a face (eg. on the saxophonist, on same double page than the pen test); and I often roll the ballpen point very tilted to get extra thin line and draw a silhouette prior to darken lines. It's a hard training 😺

@darekpages Hey, I really like traditional ink and nib; but they require a desk and something to wash the nib. These are done in transport, waiting rooms, on bed/sofa, etc... A single pen is what I'm limited (and one that can fit within the page of the sketchbook is better).
About the test page; yes: all the things I tried were pen I found around on desk of other (office things) I visited during the holidays. I was curious. I like pen that cost less than 2 Euros like my Bic orange thin. ☺️

@matclab 💜 Thank you!
