When doing traditional art, I mainly use a non-photo blue lead, so I dont have to erase. I ink with 102 & 107 nibs, a #2 kolinsky sable brush(for fill-ins), Koh-i-noor technical pens, and occasionally a C-5 calligraphy nib. I use 2 ply vellum finish bristol. When I dont feel like messing with inks, I'll use Kuretake Millennium micron pens, and a PITT brush pen for fill-ins. If I mess up, I use Bleed White to cover up mistakes- depending on how severe the mistake is.
However, over the past year, I've been working digitally more. I use Clip Studio to do my initial drawing & inking...I use Frenden's inker brushes to achieve the line quality that I have. I then import the art to Photoshop(since I dont like Clip Studio's gradient tool, and I tend to sometimes use gradients a lot in my backgrounds) and color there(using cel shading color style). I have a wider variety of texture & effects brushes in PS, which allows me to work faster. I use a Wacom Intuos tablet- I used to have issues myself looking at the screen and trying to draw but my desire to wanna ink and color using a tablet motivated me to get better. I do my lettering in Illustrator, because I'm used to the nuances and finishes of that program.
