Thank you everyone for the replies, sorry it took me a while to respond back... It's been a bit of a hectic week! I tried to redo the inking for the same image (the HP scene) after taking all your tips and advice into consideration (line weight, contrast, white auras, textures etc). While I don't think it's all that great yet, I think it's much much more interesting than the first try 
@alaingrey thanks for pointing out the textural inking from This One Summer. I definitely want to experiment with that more because overall it really does look more organic and compelling. I mean, it's still little too advanced for me at this point haha but goals amirite? I really admire Tamaki's ability to layout space though. I think even if she used flatter textures in the page you posted, your eye would still travel the way she intends because of her use of negative space. The lighting in those 3 panels at the bottom? Ugh! Also, thanks for the overlay tip, I can't believe I didn't think to use that xD
@Bloomer Thanks for the reminder, I actually do struggle with getting started on things. Especially when it involves new techniques or skillsets because I get scared that it won't turn out how I want and it just ends up frustrating me. But ya know, can't improve if you're not failing! Do you have any tips for laying out scenes in BW? I think the pacing in the page you posted is nice, in your experience is it all too different when laying things our in BW or colour?
@joannekwan My god, line weight IS my best friend! I wasn't sure if I wanted to use uniform weight for simplicity or whatever but it really is a lot funner to ink with differing weight... Even if at this point I'm not utilising it as much as I can. I don't really have that many questions now but is it ok if I hit you up sometime if I have any more? You guys have given me so much to think about and try already so I'm just really keen on experimenting and figuring out what works personally.
