Luckily there are a few of us who are prepared to be different. Tend to get ignored by the crowd who are only interested in locos painted one colour, and then only if it undergauged and made in China.
The Disc World layout is still being exhibited, very successfully I gather and not just model railway exhibitions.
The job of the artist is not to replicate what is there, but to interpret it and more importantly make people think. Easiest way to do that is to be different, and have a bit of 'shock' in it. It might(in fact it will) go over the heads of some people, but those who see beyond the initial impression, get a lot more out of it. Picasso said that when the camera became widely available, he turned away from 'traditional' painting as the camera could create an accurate image easier, and possibly better, but as an artist he could bring out something else. I think this is even truer these days with digital cameras, and although there are a lot of good photographers, it is more the machine than the person doing the work. That 'classic' photo is normally one of tens possibly hundreds of photos taken at the time, and then selected. It might then get modified, no problem there, in fact that is possibly bring more artistic creativity into what has been created by a machine. A pin hole camera is as good a start point, as one of my rat uni would claim.
I am trying to merge creative artwork and model railways. One of the differences I have noticed, is how much we are prepared to share in model railways, yet many artists are very protective of their ideas(which have probably evolved from ideas elsewhere anyway). I find the art world very disjointed, and a lot of artists grumbling no one is working together, helping each other, and many just trying to promote their own artwork. Online forums for artists seem to be rare, and not very inviting.
