I'd strongly recommend the article "I Will Not Read Your F***ing Script" (warning, profanity) for some thoughts on criticism and why it cannot be expected. I think it's a really good insight!
Sometimes, when people ask for critique or reviews or help, I have the time and I will do everything I can to offer it! A single critique post takes me HOURS, and when someone says "wow, thank you, this helps so much!" all those hours are definitely worth it!! And I really appreciate everyone who's taken the time to tell me it was helpful for them. ;u; But I can't do that for every comic that posts here, and neither can the others -- we all have comics to draw!
If someone says "hey, read my comic and tell me what you think, thanks" they are asking for tons of effort on my part without making any effort themselves, and that's what bothers me about critique in the community here. I'll occasionally see "I'm having trouble with the anatomy here, can someone help me, what am I missing?" or "I feel like my opening chapter's pacing is too slow, what do you guys think?" and that's cool!! Even "I'm new to comics, what am I doing right? What could I be doing better?" is a direct request for critique that I'll offer my thoughts on if I'm able!
But I'm not going to pour hours into an in-depth and thought-out review if the person may or may not actually want critique.
Also important to consider: Critique is not helpful to someone who doesn't want it! Pruning is useful for plants but it has to be at the right time or you'll snip off all their flowers. If a thread is "comment on the above" then no, I'm not gonna give them an in-depth (or critical) critique, because no one there has asked for it and I don't know if they want it. Unsolicited critique is rude and unhelpful. The part about "don't cast your pearls before swine" that a lot of people don't think about is that if someone doesn't value or have use for pearls, then you'd just be throwing rocks at them, no matter how helpful you think you are.
So, I will certainly be honest and give the best and most thought-out critique that I can if someone has asked for it and I have the time to offer it. ;u; But I'm not gonna assume that my critique is so great and important that you should want it whether you've asked for it or not! If the Tapastic Community wants to foster greater and more in-depth critique, it needs to make spaces for that kind of critique because you can't just drop it in anywhere, and there needs to be more than the effortless, "hey, read my comic, let me know what you think" that casually assumes that thought-out critique is not a big endeavour!
