A Watercolor Challenger & Being Drawn to Particular Subjects When Making Art

It's so fascinating to me how each artist is drawn to a specific kind of subject. I think it says so much about them. In my opinion, what makes an artist's style is, not only what physical supplies they choose to use for their work and how they choose to use them, but also what subjects they are compelled to represent and the way they choose to represent those particular subjects. It's the combination of all of these elements that make the viewer of the piece feel a particular way or think of a particular idea. In turn, IF the viewer connects with a particular artist's style, it says so much about THEM, but that is another story...
I am still working towards finding my particular style. Even though my painting style is slowly starting to show and I have learned so much about what supplies I enjoy using most over the past few months, I am still unsure about what subjects I want to specialize in and what feelings or ideas I want to transmit with my work. I honestly feel like an artwork is mediocre if it doesn't effectively transmit SOMETHING to the viewer. It could be an amazing artwork, but if it fails to transmit an idea, it is just a ¨pretty¨ picture. To me, art isn't about just being ¨pretty¨, but about having meaning. 
Anyway, I mainly wanted to talk about why I felt compelled to paint a car. Not only did I feel it would be a great challenge because I haven't really tried to paint anything mechanical, but I do feel drawn to cars (especially older models). I love this quote included in the book Invisible Monsters by Chuck Palahniuk: "Nothing of me is original. I am the combined effort of everyone I've ever known.¨ It's so true. 
Everything we are is a result of the things we have been through and the people that have affected us somehow in our lives. I will probably always be drawn to cars because I have an older brother and used to have a father that loved and fixed cars up. Throughout my childhood I played a lot of racing games on either computer or Nintendo. I had my own Hot Wheels to play with my brother because he was my only sibling. Ever since I can remember, my basement has been filled up with old car parts and maintenance supplies. To the day, it is a relief that whatever happens to my current car, I KNOW I can call my brother and he'll have a pretty good idea of what the problem is. It doesn't take a rocket scientist to know why I decided to paint a car and not a vase of flowers.
I had fun with this one and it was a great way to continue practicing my use of masking fluid. Today, I am going to the art supply store to buy some oil painting supplies in order to make a painting next week! More about that later. If you are still reading this, thank you so much for visiting and have a wonderful day!
