awe thanks :3 For drawing digitally these days I use an app called ProCreate on my iPad along with an Apple pencil. It's feature rich and has a load of awesome brushes to really get any texture you want in there! It also exports directly to a PSD file to do final touches in Photoshop if needed.
I've touched on using it in previous posts (and I'm going to touch on it a little in my Thursday vlog this week, too) but I've yet to do a straight up software tutorial - I'm not sure I'd be great at that, lol! But if she has any specific questions then I'm always happy to answer to the best of my ability!
