I don't really think your comment was rude, but I do think it might have been better with a little more clarification. I also think comments should be directed towards the image more than the text the artist includes. It DOES say "Your helpful comments for improving this image" in the feedback section. Naturally, I wouldn't expect everyone to offer constructive criticism on my images, but I WOULD expect them to concentrate their comments on the image. If they had anything to say about any text I might have included, I guess I would prefer that they mention it as an aside from their comments on my work. All of this is, of course, my opinion.
