If’ you’d like to submit a painting or drawing for public critique, send me an image of it. I will either respond with an email telling you why I don’t feel comfortable doing a critique of it, or I will post it on this site with my feedback (with, potentially, thoughts from commenters as well). I won’t be mean, but I will give my honest opinion, which some people might find painful.
A few caveats: Files should be less than 100k in size.* Make sure it’s a decent photo or scan, not one full of glare or other problems. I’m not qualified to judge most abstract or political work. Don’t send your first ever painting; do 10 or 20 or 100 more and send the best one of those. Don’t’ send joke images; I’ll only add you to my spam filter. Send only one image. Send your own work. (Yes, you can probably fool me by sending an image of some classic but not well-known painting. Big deal.) If you’re a better artist than me (and lots of people are) then I would not be the one to judge your work.
*You can find out the size by selecting the file (click on it once) and choosing “Properties” (Windows) or “Get info” (Mac) from the File menu. If it gives a size in megabytes (MB) the file is way too big. If you’re not sure how to make the file small enough to send conveniently by email, you will need to change either the pixel dimensions of the image, the amount of compression, or both. Changing the number of dots per inch only affects how it will print, not the file size. Try saving the file in JPG format if it’s not already that kind of file. If this paragraph seems like gibberish to you, find a teenager who knows about computers and ask them to make the file 100 k (kilobytes) or less in size.
