This is just a quick note, as I've just tripped over the fact that Daniel Lieske has the 9th chapter in his long-standing webcomic (er, graphic web album? comic really doesn't do this justice!) called The Wormworld Saga available for all to see and read.
The Wormworld Saga follows the adventures of a boy called Jonas in a parallel world, which he entered through a picture/mirror/empty frame in his Grandmother's attic. So far so default a setting, what really sets this apart is the storytelling, but even more it's the artwork by Daniel which drives this. The drawings, in an unusual, vertical format, are exquisite, a visual smorgasbord of impression and references, really bringing to life the cultures, settings, and creatures in the story.
But go look for yourself - you will want to start with Chapter 1 if you have not read this before, there are no real jumping-on points, and it's very well worth starting at the beginning!
I notice that Daniel meanwhile also has a Patreon page, so if you like what you see you could, nah, should help him with making ends meet whilst he crafts these great stories (or you could always visit the shop, and buy the books, or merchandise, or the game to go with the on-going story!).
Anyway, enough hyperbole. Go look, and make up your own mind!
