Isn't it sad that so many great and fantastic ideas just get lost in the brink of time?
I believe most people in here don't ever take some time to look closely, to really discover a picture and extract the whole essence out of it. Maybe it's because they get loads of new exciting artworks every day and don't have the time to look at them all and discover their true reality.

Just take yourself an hour or a half a day, or even ten minutes would do to just contemplate and meditate over an artwork you really like. Then leave your coments to let the artist know what you discovered.
That will help you AND the artist, because you will learn more about art itself (and about you, if you take the psychological point), you will have more respect about a great artwork and it'll fire your imagination so you come to have great ideas and inspires you to do great art yourself (I never meditated on an artwork and didn't at the same time inspire me to do art myself).
You'll help the artist to show him that his art is taken seriously and that people really SEE it, rather than just look at it and say "wow!" just after 10 seconds staring. I know it's better than ignoring it. But if you really see art and tell the artist what you discovered about his picture, the artist get's great ideas by himself and gets inspired to make new art. It really helps him too, because you show him what to make better and he gets more and more experienced over time. He sees how much his art is worth for other people, and so he loves making more and more for people to enjoy.

I hope I've motivated you to just take yourself a few minutes to really SEE an artwork, regardless of if it is made by an art-crack who get's a thousand comments a day or if it's just from a beginner, who really needs your encourage and support, to improve himself and to see his art gets attention. If you like an artwork and want to discover what's behind it, or experience it's true power, then take the time and do it!
