There's the other side to critiquing, which is learning how to ask for a critique.
Questions I like to ask so that I can explain what I'm looking for (from Art & Fear, but there are a lot of ways to ask):
- What am I trying to achieve?
- Did I achieve it? (most likely other people can answer this, but if I haven't at least tried to answer it myself, that and question 1 helps me ask for specifics)
- Was it worth it? (nobody can tell you whether it was worth it, but if, let's say, you are doing it to explore certain subject matter or a new technique, then you can say it was worth it, and people will know to comment and help you on that)
Even though you say the image is not for anything, it seems like your image must have a particular market that is NOT me. It's hard to just jump in and talk to you about the technical aspects, which are fine, when I feel that the image is misogynistic. To turn Dorothy into a heavily made-up woman wearing girlish clothes, sexualize her, make her helpless, and then put a dead look in her eyes, achieves that perfectly.
It sounds like I'm mad, but I promise you I'm not. It happens to be a really clear example that maybe it's not going to help you if you're not specific when you ask. This is some kind of conception of Dorothy that has nothing to do with the Wizard of Oz in any form I know, so you should at least explain if it's something entirely different.
Suggestions on how to critique in another thread were for teachers of art. I'm not a teacher, don't plan on being a teacher, and none of the people on this forum are teachers except for the svs instructors. I can't be expected to respond in that way, and can only respond in terms of being a fellow artmaker that happens to be working on the same character, and then possibly as part of a market that you're going for. So you see, I can easily be honest, but have a feeling that this is not what you were hoping for.
