I vote for the artwork being inside front cover, assuming the font will be a colorful one. Often times I've been grabbed by black-and-white intricate illustrations opening the hardcover as if they are inviting, "welcome, this is what you're getting into."
I like the shading of her hair and the flowers. All of them are a little different in shape, must have taken you a long time. Drawing one flower/leaf at a time explains the variations a bit.
I Thought It Would Be Zombies looks neat! I'd love to read the final comic book. Btw, the art style reminds me of a graphic novel series I've read somewhat, didn't finish, and now regret not finishing - Saga.
About that shape language, you can write art-theory and stuff like that on hive, you know. You clearly have the knowledge and it might help a lot of aspiring new artists.
I've been leaning between inside front or back cover so I appreciate the vote! Back cover reminds me of some old Savage Sword of Conan magazines which often featured some nice black and white back cover illustrations.
Writing more tutorials & discussing art theory was absolutely a motivation of mine for starting the Creating Comics community. As with everything I just need to find the time and energy!
Ah, I haven't noticed the community before.
I hope you do find the time and energy.
As much as I can read or watch, I believe learning from someone I can interact with and who's in the business for a while will be different.
