You do not always need to use strobes to shoot classical portraitures. In fact, you can produce very good and natural looking portraits using available light. Here is an example: http://www.pbase.com/image/28555770.jpg
Sometimes in character type portraits, you may need to think of how to present the photo. It may be more impactful to show it in monochrome. This is where you need to decide how to do the conversion. You need to see how the skin tone translates and how details and overall texture come through in the b/w version.
but it can be done if you pay sufficient attention and care when lighting and posing the subject. The trick is to tilt the glasses a little downwards and check constantly in the viewfinder before triggering the shutter.
Good portraits need not be of beautiful girls only. The challenge is always for the photographer to portray his subject. Hence, he needs to find the elements that will flatter his subject. Men can be portrayed as good looking, strong, determined, etc.

Valuable tips..you have there. Conducting lessons somewhere ? Personally, I must say your images are traditional portrait shots. It's too 'formal' or 'serious'. Have you tried modern portrait shots with poses and 'different' backgrounds ?
