Given the specific instructions provided on what we're about to draw, I'd say some of the main important things to consider are the use of positive/negative spaces. As this can make or break the main purpise/goal of the exercise. Too much empty space can make an illustration feel incomplete or unbalanced if it does not draw your audiences attention to the major details you wish them to see or feel. Having a preliminary rough idea of what you want to portray will allow you to focus on other factors such as composition, lighting, etc.. Also, what's the purpose of the exercise? Are you projecting something personal? are you doing a study on something specific? What's the end game exactly?

Allow drawing to happen. To flow. To sporadically pour forth from your pen to your wrist, gimbaled to your elbow, metered by the heave of your breath and the wit of your eye. Stay away from the mind and its machinations and the troubles it stirs. Feel it, see it, breathe it. Don't judge it or plan it with rulers and guides, or compare it to what it should be and all the worry that brings. Find what attracts you, look for what turns you on, and dive head first into it with abandon, making mistakes all along the way. And as inevitable as the dawn, and with time, all the elements and principles of good design will crest, composition, texture, style, tone, line, and most importantly- your voice.

Have the end in mind! With any creative project you have a purpose or goal, whether it is to express a feeling, or tell a story, usually a little bit of both. When you have the end in mind, a lot of the questions are answered and you will be more inspired. However, learning art is about HOW to get there!
I like to help students apply their own interests, desires, passions, skills and experience to be more creative, then to help you to see your own art and style differently. Along the way, we will naturally explore techniques and styles that help you improve and become the artist you want to be.

The first thing to consider is the orientation of our format. Simple as it may seem, this decision will influence the rest of the creation process. If our model or figure to be drawn fits better in a horizontal or vertical rectangle, we can also force the orientation for specific purposes, but it is essential to always take this matter into account to develop our composition.
