Speaking for myself, I think when working on a portrait picture the important factors to realise are that the main focal point is the subject or character under observation. Therefore the three most important fundamental elements of any image are composition, lighting and texture. Images containing a large scene can lead an observer to key areas within the scene through linear perspective alignment. While working on close-up work I concentrate more on expression and detail. A smile, frown, raised eyebrow or anything that breaks the stiff lifeless pose. The idea is to breathe life into the subject. When working on a new character I often work with a mirror next to my PC and find myself pulling various faces and trying to duplicate the expressions. This exercise gives you a good insight into basic facial expressions. Experimentation is a good route to a good image. Practice, patience and time is all thats needed, above all remember that the image is for you! .. It doesnt matter if the image does not get the feedback you anticipated, just stick at it and remain positive. Good luck! Cada
