I kinda like A the best. The picture could use some uninteresting space that the eye doesn't have to look at. It's a little sterile in A though. Maybe if the edges were more organic it'd look more natural and less deliberate. That's my thoughts It's a lovely lineart though ^^
<.< I realized I left the ivy layer turned off that was along the banister, so I'll be doing another update soon-ish
THANK YOU!
