Mostly it's just a game of who you know and who you blow, to put it bluntly. Meaning people tend to gush comments on people they like, regardless of if the image is technically or artistically good, and they ignore everything else regardless of quality. Recently there was a poser pic put up by an artist that had some very nice comicish postwork. Before I looked at it, it had around 10 "OH EXCELLENT WORK" comment as soon as I saw it I noticed that the artist had made a mistake with the coat the character was wearing. On one side the hip plainly poked through and on the other a leg poked through. Applying some morphs the jacket came with would solve this. I put this info in my comment. Two days later the artist posted another pic which was more of a comic cover, same cool post work, same mistake, over 14 comments not one mentioning the flaw. You can find all kinds of examples of this kinda thing in the galleries. So my advice to you is this. If you think something you do is cool enough to put it up in one of the galleries the do it because you want to share. Don't do it for validation because if you do you won't get it and you'll just end up being frustrated all the time. I know I went through something similar after I first got poser. Now I do my pics for me and barely bother with the posting in the galleries anymore.
