I wish I could help you, but I lack in many areas when it comes to drawing (mainly clothes, backgrounds, body position and patience), and I am still waiting to get my tablet. Not ideal as partner.
But I kind of understand how you want to you want to find the art style that matches the images you have in your head. Maybe you should try to describe the images you have. Is it a realistic style or a more "comic" type? Is it colorful? Black&White? Is it dark? Is it emotional? Is it the Korean type of comic pages or the Japanese ones?
I do the japanese type, and my art style is like this:
And this is a sketch of the comic I am working on (to show you boys):
Is it close enough to the art style you are searching for? Probably not dark enough... -v-' (I never tried it, so I do not know)
Either way, I wanted to say that I find the genres you write interesting and I like how you aiming to get better at drawing .
I wanted to ask, do you read/write BL(boys' love)? I was thinking that we could exchange some feedback and advice on each other's story if you do not mind (and if you do not already have enough beta reader/proofreader). I am kind of a writer too, so I know a little about this and that when it comes to novels. Would you be interested?
Sorry for the long comment, and thanks for taking your time to read it ^v^. Good luck with your comic!
