You know what I hate when I ask someone a drawing question is when they just answer with keep drawing. That's the laziest stupidest advice I hear. The person isn't learning shit from that. You could continue to do the same thing for a while and never realize it until it's pointed out to you. You learn way more from actual critiques than that bullshit.
I think it completely depends what the person is asking and what it is they plan on doing. 90% of the time the answer is to keep drawing for an array of reasons - one of them being that the artist themselves has to learn how to identify their own mistakes, and this will mostly come through observation of life vs. observing their own work.
The problem with critiquing is most people can't even critique
well. A huge portion of people will simply answer with what they personally feel will make a particular piece better. Having someone to critique would take an investment of time from both the artist and the one making the critique to understand the goals of the artist and what they're missing in any particular area of their work; counting all the various "foundations" this could be entire essays passed back and forth between two people.
I mean, even when it comes to anatomical errors - if you're asking another artist they will only be able to explain as far as their own limitations, so you'll be learning their mistakes too. This is why going to the source (life studies) is always the best place to go; there are no mistakes attached.
Other times there are artists who want the results without wanting to put the time in. If the artist isn't willing to take time out to examine why their own work is wrong, why should someone else?
Critique is plenty helpful but you reaaally need to pick who and where you get it from because not all advise is good advice - same with this lol.
