Welcome to Gaia! ::

the person above me put it pretty well, i think
nitpicking on styles is pretty awkward territory bc different artists have different styles, but tbh if u dont like someone's style it's not rly necessary to say that
but it's a thin line and u could pass something like wrong anatomy off as so-and-so style
there's also the matter of whether or not it's just the viewer's opinion and not technical aspects

i'd like to think im pretty open to criticism
if someone started bashing my style or telling me to do something else that'd just be rude
i'll accept any criticism as long as the person is respectful and not rude, and provides opinions on why they think something should be changed basically any actual critique and not flaming lolol

tldr criticism i would accept is stuff like "your chibi's head seems a bit big, i think it looks unbalanced" cos this has why thte person thinks so as well
stuff i wouldnt are things like "you should work harder on next time" or "be more consistent with ur styles" cos this is rather opinionated? and the first one is just //sigh

So, would you accept critique on someone who you consider to have little skill as an artist?

I do all the time. Well, when I have time to draw, that is. My husband is not artistically inclined in any sort of visual media, with an exception to being able to draw what he actually sees to a fair degree, but he can still tell me if something's off. And he's not exactly shy about it. (I really should listen to him more often regarding not going stagnant. >.> )

A person doesn't have to practice a trade to know the workings behind it. If they can tell me what is wrong and how to fix it by referring me to sources that cover the topic they're addressing, why should I discount their critique just because they don't/can't draw?

Art is generally intended for an audience, so if you don't want to listen to or appreciate your audience, you soon won't have one.

When working professionally, of course you need to listen to those less skilled than you. A professional artist who is being paid has to listen to people of various (or absolutely no) skill level in order to do his job and will not have his job if he doesn't in the same way that if a restaurant owner threw out all the complaints of her customers about the service and the food on the basis of, "How long have you been in the culinary industry, hmmm?," she would lose her business.

When trying to build an audience, yes, you should listen to those less skilled than you. You as an artist are promoting more than your artwork. You're promoting yourself as a person, and clients, fans, customers, they don't ever see you as "off duty."

When working on something for personal use only, just for you, alone, to enjoy, and yet somehow someone comments on it? Yes, you should listen to them even then. You aren't always going to be working simply for your own personal enjoyment, so it's useful to be aware of what others think of your work for when you do decide to work for others, even if it is stylistic nitpickiness. What if a complaint about a point of your style comes up more than once, and then later when you need to do work for not-yourself, your deaf ears have held you back from being able to really knock it out of the park?

Does that mean you should always change your work according to what they say? No: you are the final decision maker, and it's up to you. Of course, if you're being paid to make the changes, then make the damn changes.
