Greetings..
I will begin with a disclaimer, the following is only my opinion.. not an assertion of fact or a contradiction intended to incite conflict.
Art, as i understand it, involves some aspect of creativity.. perhaps, as we evolve in our Martial Skills, we also evolve into the capability to create.. where we can expand beyond mimicry into self-expression consistent with the principles of the Art..
I have seen many skilled "artists" doing forms and/or fighting where they utilize variations of their style in such a manner as to be observably effective and still fit within their style's conceptual limits.. i feel they are "artists"..
It is one thing to master a set of skills (mimicry), another to add your own spirit/flavor to that skill set and still be recognized as the same effective skill set.. in the beginning we mimic to learn the intended value of the skill set, it becomes art when we internalize it into a similar skill set that is optimized for our own experiences..
Sometimes, i think we tend to "lower the bar" to accommodate our desired perception of ourselves.. i largely consider my self as a "Martial Arts Student", working toward the "artist" level of understanding and skill.. i have minimally modified certain aspects of certain forms, presented the modifications to recognized authorities.. i have been corrected, and i have been told that a couple of the modifications are on point.. but, i think that was more blind luck (and my nature to seek the application of any movement)..
I also think it is important to let recognized authorities decide what we are, rather than claim a title.. my students like to call me Sifu, i prefer LaoShi.. or, as i am becoming more comfortable with the nuance of meanings, "coach".. but, so help me, i don't want Coach Ross to know i would affirm that title, he can be SO annoying.. but, i respect his annoying mannerisms..
Crap! now, i'm just rambling.. i think we argue of preferences.. and it is unfortunate that we disrespect people over preferences that are of no real consequence to our own preference.. some people despise cultural and philosophical attachments to their perception of MA.. others imply it is just that that raises martial skill to an art.. but, when you're sitting on the curb holding a hand-full of your own teeth, it doesn't matter whether it was skill or art.. you got schooled..
Be well...
