Having a room that has a plethora of art is something that only a person who loves this would appreciate. There are many who do not enjoy this form of expression and prefer clean walls as compared to have personalized canvas prints tell a story on the wall. But the point here is that people should try and inculcate this form of articulation to get to what was in the artists mind.
One may just put it down to modern art, but nothing is as it seems to the trained eye. For instance one may look at color perceiving it to be a hot-potch of this and that, but it could be the story of a broken heart or even of conflict, or anything really. To get custom artwork created one would need to find the right person for the job.
To put it in a nutshell, if one would like to have a tattoo on the body, one would research and conduct enquiries about the person and the accomplishments and here too it would be a good idea. Once the right artist does the job (after whetting through the rest), you can sit back and enjoy the resplendence. So, what does make good art then? It is difficult to stick to a simple answer, as it is based on an individual’s perception of the piece!
