After a long search and experimenting with a lot of media, I have finally found the style I was looking for :)
I have decided that ballpoint pens are for me, and that I will continue to make a series of ballpoint pen drawings in the future. I'm going to build up my portfolio and eventually have all of my work have a unique and consistent style. And also, I'm going to eventually take my other art off of my portfolio.
I know I said that I'm not going to pursue art as my main career... and while that is still true, I do want to have it on the side. If it ever turns into my main career, then I would be more than excited! But for now, I am focusing on it as a side project.
I feel pretty inspired and motivated to have a more complete and consistent portfolio :)
