The sketch tag

Hello, I've been browsing through images and finding a lot of rough illustrations that haven't been tagged as sketch. I'm only interested in seeing finished drawings, but if blacklisting "sketch" doesn't work, I think that's a problem with the website. I've been tagging the ones that I deem to be worthy of the tag, but I am unsure about these two:

What's rough: clothes, a lot of stuff around the character, etc

What's rough: wrappings on the left hand, waist clothing piece, a lot of the torn clothing, etc

According to the wiki definition of sketch, they seem to apply:
A hasty or undetailed drawing or painting often made as a preliminary study.
Traits of sketches include rough lines, basic coloring, and left over structural shapes.

Before I start tagging similar images (and trust me, there's a lot), I'd like to ask the opinion of more experienced users of the tagging system. I'm sorry if I made a mistake up to this point while tagging

The examples you've posted may be rougher than you'd like, but they're clearly finished and don't have the extraneous lines that the word "sketch" would imply, such as post #2720851 and post #2722791.

Meanwhile, you've been tagging posts such as post #2722170 with sketch which I completely disagree with. The outlines may not be laser sharp like a game CG would, but it's a clear stylistic choice and not an actual sketch.

Got it. Based on this, I will undo my changes, if they haven't been undone already. Excuse me for the improper tagging.

On the post that I've tagged that you've linked, I added the sketch tag because I thought it matched the wiki definition. I will link the sketch examples you have showed me and the posts that I tagged incorrectly on the wiki explanation for a clearer distinction.
