Depends on the person really. If I know a guy actually consistently does interesting descriptions ( which you can usually gauge just by reading the user comments ), I'd take a look at it. Otherwise, no, I'm in for the art. Don't judge me for it please!
Yes, I always read the description It kinda represents someone's work and the story behind it. Also, I am sometimes interested in what media na artist used to create some traditional painting.
But somehow, I ALWAYS skip the part that someone used somebody else's lineart and I always comment how good the lineart is, but the colouring could use a bit more shading :/ And I end up looking like an A-hole
I do read them. Unless its some lore on a certain thing, which i will read if I'm interested. Usually the descriptions is about how the person came about with this work, or the reasoning behind certain things.
