from a design standpoint, if you're looking for really solid critique on design elements, then frankly you probably aren't going to find them here. the reason for that being that 95% of the designers here are really new designers and couldn't tell you specific design related issues if they wanted to; they just don't know them yet.

of the people who have been around long enough haven't progressed at all because the void, ironically, seems to be full of designers either unable or unwilling to try to make any progress and actually learn good design. they all make the same types of stuff, and the it's a circular cycle of copying eachother's work. this is why almost everyone's tags here are nearly the same exact style (some sort of smudge or c4d spam or fractal spam, all of which rely entirely on the quality of resources used instead of using good design elements to create a piece themselves). the only comments you are going to get usually is how to turn whatever you make into one of those styles, because that's what they know, and that's what they think is good.

there are some people here with some skill, don't get me wrong, but those people probably don't post often because of being discouraged by their posts being disregarded by new designers that hear "omg that's awesome" from a few of thier friends who are also really new and don't know better, and when they hear the "actually it's really not good, here's why..." from someone who knows better they prefer the positive crit and keep making things in order to get those remarks again. hence no progress.
