Well, i did draw some oneshot yuri before so my advice is just to
- make sure you have a solid plot (so the reader will know what exactly is going on and you can avoid plot hole)
- anatomy. Your art is not that great? No worries, just make sure their body movement doesn't look weird cuz its hard to read with that
- do you have a plan on where are you going to released them? If you want to make it a hit asap then I'd recommend post some skits or stuff on social media with your charas before going straight to publishing it if you want to have solid fandom first
- I'd advise to have a partner for backup incase you are having an artblock, need a proofreader, etc
- if you are not used to drawing on laptop then you can try using phone or tablet first. In my case i just use my phone and ibis paint
Anyw, this is just my personal opinions. It's not like i did make a hit with my story but i hope this help!

guys one day i wanna draw a bl of my own...do u have any advice for me ( i suck at drawing and never draw on laptop before)
