Close up Portfolio planning

I want to capture some close up images for my portfolio and try to capture the eyes of animals. To do this I will need to use the following equipment.

• Canon 400d
• Canon Zoom lens
• Monopod / Tripod

I can capture these types of images at Twycross zoo as I should be able to get there every couple of weeks as being a member I can get in for free. I will use the monopod or tripod to help steady the lens as will need to use it at its full zoom when taking these shots. I will aim to focus on the larger animals at the zoo for this as i think they give the most dramatic results.
