Thanks for your comment @angelro :)
I think what's important is the will to create, more than the way we do it.
I mean, there are exuberant and easy- to-notice ways to create, like painting drawing, singing, but the 'gift' you mention can be expressed in a myriad of different more common and discreet other ways.
I'm pretty sure we can find it in everyone that have to solve problems, and manage these situations with their own tools and environments: parents with their kids, plummers confronted to unreachable leaks to plug up, etc.
We all get that thrilling feeling when we find by ourselves a solution to a problem in our lives...
That's the same feeling we get when progressing on a painting or in any artistic domain... Except that in these domains, problems encountered are somewhat artificial and superficial compared to every day's life :)
Oh ! And about your last question... I'm not sure: my artistic culture and knowledge are really bad ! :D
I call that surrealism, because I put some realist cover above spontaneous abstract art, but I'm pretty sure someone else with better art education would find another label to stick to this kind of work :)
Anyways !
Have a nice day ;)
