This is a very beautiful piece, Isabel, great personality. I'm scared to see what you can do with the pastel. If you're not struggling with them, lie and say you did!
If you're lucky, you will go through different stages in your life, then decide which is best for you. To make up your mind this early in life is, imo, a mistake. I applaud you for working looser, and you've done a great job with it, but there is nothing wrong with experimenting. There seems to be a similar discussion in my recent thread, so I'll discuss my personal experience there rather than take away from your
thread.
I'm sure you will do great things whatever you decide to do.
