As soon as you are satisfied, start assigning soft and hard edges (Shift + right click the menu in Edge mode). That'll help in the future when texturing. For example, hard edges on the toes will look great with a metal texture (Fig.21).
Another way to add new objects is to create a simple primitive plane (Fig.22).
The creation follows the same pattern from here onwards. You need to add the details step-by-step. Now it's time to put our belt straps on their own layer. Layer systems are very helpful if you want to keep things in order. It also helps you to hide objects or switch Transparency on and off (Fig.23).
Always make sure that you have a picture of your concept open. I have two monitors and put my concept on my second monitor (Fig.24).
