I've inked a few things digitally. i did a few covers that i had to do really quickly and they weren't sellable images. Also i inked a recent Mass Effect thing digitally (8 pages). It was for FCBD next year. I did that entirely digitally to see if i liked it. It was much faster but i don;t think i'll make a full transition to digital. i like the challenge of using real ink and brushes and like you said, it's always good to have originals. But if i have a really tight deadline i'll go full digital.
Thanks for sharing Garry. I just started trying digital because I restarted working full day at my not-drawing job and I draw comics just in spare time, so I'm trying to see if digital can help in speeding up things
