When doing character portraits you should bear in mind that as that character advances in level his/her equipment will change. The character will find or buy better weapons, armor, items, clothing, etc. The characters are assumed to age a year each level. This will have little effect on longer lived races Elves being the most extreme example. You may wish to add bits of wear and tear to older equipment and to the characters themselves. Bear in mind that magical healing will often minimize scars etc.
