Abstract modern art seems to have some things in common with some kids' art: focus on materials, color, texture, perception; and representational art may focus on symbolism rather than realistic rendering. There's also an authenticity to art that is created for personal expression without worrying what other people will think about it.

It's hard to capture three dimensional physical art in two dimensions and/or digitallly, even more so when the art is abstract. The context and interaction with the physical environment can also be important.
