I've been inspired to create a piece based on the zOMG manga, and I really wanna learn how to recreate that dotty look on GIMP.
Check out the last panel--the one with Ian:
I love how the dots aren't uniform, but look more like a gradient. How on earth do I achieve this exact style? I'd love it if anyone can send me a tutorial on how to do this, or even explain it to me themselves. (Remember, I use GIMP, not Photoshop.)
They're called screentones, and if you want to do that digitally there's a bunch of places on the internet you can get them...either for free, or paid patterns/textures. I don't know any offhand since I nabbed a bunch of screentones ten or so years ago, but I'm sure there's still some free ones around. You might find some people made on Deviantart.
