It seems like in this picture, it's just after Garry burns Mary's portrait. Ib is terribly upset and Garry tries to comfort her. But being burned freed Mary from her suffering, and seeing Ib so torn up makes Mary incredibly sad....but all she can do is watch.
Yeah, I've always sympathized with Mary, since she was drawn as a child, and hand childish thoughts.
When you're a child, you think everything is so simple, and you act on impulses that adults don't. That's why Ib was able to walk through that place without too much mental scarring (though there were lasting effects...like a fear of palette knives) while Garry was completely and utterly terrified. Mary was drawn as a child, a lonely, pitiful child. She was selfish, as most children are, and wanted friends to play with, friends that wouldn't do everything that she asked. Her mind became twisted in the Fabricated World, and she acted upon all of her impulses. Unfortunately, those impulses got her into a lot of trouble, and in the end, she had to be destroyed. But she was forever grateful to Ib and Garry for doing that, and at seeing Ib so torn up, perhaps she decided that she would go on, and protect Ib and Garry....almost like a Guardian Angel.
you absolutely dont think too much into things. this is an evaluating opinion on the piece. and if you could see something the actual maker didnt notice, its pretty much art itself. real art makes you think and consider sides of something you dont actually see. thats the reason why i detest calling smears and cascades of unrecognizable colour "art"...
art is something that makes others want to make art. so is the beauty portraid in this picture. emotions that are felt while looking at this piece make it even more so. sadly, i cant give a critique on it, because its not enabled. but ill express how wonderfull it is none the less.
Ps.: you should put the comments of kierax away into a safe place. words and concepts like those really add to your work here. the sum of the worth of a painting is allways the words people can say about it. the more in-depth and meaningfull, the more valuable.
