Stepping outside your comfort zone
Artists are often given the advice to 'try something new' when they are discovering their style or voice. MY advice is: If you're gong to try something new, don't try a bunch of something new. For instance, if you're working with unfamiliar subject matter; don't use materials you've never touched before.
SAMPLE: I've worked with pencil, markers and ink all the time. It's one of my favorite go-tos. So when I took on the daunting task of rendering this lovely pice of French architecture, I stuck with materials I was comfortable with using.
That way you are not struggling with two new elements. Don't make your life harder than it needs to be or set yourself up for failure.
