You guys made some good points that I totally missed out on. Namely, what it is I want. Truth be told, I'm not totally sure myself! LOL! I have ideas of what I'd like to see, but artist interpretation is also something that I enjoy. Here's just a few things I have considered, though:
For Anywhere, a slice of life BL, what I originally had in mind was seeing the main characters sitting in an old, abandoned building next to a broken-out floor to ceiling window, overlooking a cityscape at night. They're holding hands on the floor, one has tattoos on his arm, the other scars, which I know can be upsetting to some people, but there is a point to it given his character. One of the major events in the book takes place at a lake during a meteor shower. If that was incorporated, that would be amazing. Gen has a mohawk with dyed tips, piercings in his eyebrow, lip, and ears. One of those piercings is an industrial with two hearts. Mika is half-Japanese with long hair for the first half of the book, cut short for the second. He has bright blue eyes and usually wears a hoodie to cover his scars, and also to hide in. Both of them are in their mid to late teens. I'm open to the style, though the anime/manga style is something I really enjoy.
For I'll Destroy Hell for You, that one is a bit more complicated...I definitely want my two MC's, and four background. One is a demon who lives among the world in human form. He's tall, dark blood-red hair, sharp incisors, cut but not overly muscular. When he changes, he has black marks on his body that look like flames outlined in red. His eyes are amber, fangs, and claws. He also has horns and wings but we never see them. The other MC has thick, wavy blonde hair and ruby red eyes. He's shorter than Hawk, with a few piercings in his ears, one in his nose. He also has a few small tattoos but I never went into detail about them. Both of them are in their late twenties. Well, technically Hawk is of indeterminate age but that's beside the point. I don't even know where to begin with the background, and the style is again, open.
Background characters: a dark-skinned boy with red dreads, amber eyes, around seventeen. He wears a leather armband around the top of his right arm with three feathers than hang from it. He's a demon shifter who works for Hawk; a severe looking woman with long blonde hair and amber eyes. She's a demoness who also works for Hawk, but is also his handler. She looks around late twenties, early thirties; young woman with blonde hair with half of it dyed pink and blue. She has blue eyes and is around the same age as Hero, the other MC; finally a young man with brown hair and blue eyes. The last two are the secondary couple and Hawk and Hero's best friends, both of them outgoing.
Again, these are just basic ideas to get started. I'm open to the style, and the background, for the second book especially, is open for ideas as well. I hope this helps. If you think of something better, feel free to toss it out there as we can work something out.
Thank you, guys, for giving me advice on this. Clearly this is the first time I've reached out and have no idea how to go about it.
