"Do painters and other artist's have a first, second, third, competition?"
Yes, lots of them: The Turner Prize, Arte Laguna Prize, Jerwood Prize, the Sovereign European Art Prize....
The only difference is the prize is not a medal, it tends towards thousands of pounds/ dollars/ euros, and there is usually only a first place awarded
People always hold up art as the ideal when in actual fact its more closely related to (and arguably unduly influenced by) money and far more controversial than modelling
In fact, the money aspect of art and the fact that the art world is antithetical to the ideal that the best and most original work should get the attention (rather than the most fashionable and marketable) is one reason why I decided not to pursue it when I finished my degree in Fine Art practice
By comparison modelling competitions are taken far less seriously and are what they should be; fun and not a lot more
There is nothing wrong with competitions in modelling, only with people that take them too seriously.
