Dan, you are at a good point here on your painting. Your photo is not the best but if this is what you have then what does one do. We do the best we can.

I am afraid I can not offer you much but what I do share with you I hope it will help you to determine what you need to do.

I have made a adjustment to your photo in order that you may see how the light affects your subject. Now, you can use this light effect, in your painting and step up the value or bring the value down. What ever you prefer.

Always keep in mind the drawing being correct (no distortion unless you prefer it) the values and how you treat them and the balance in hue and temperature shifts.

This mite be a lot to think about but that is the life of a artist.
Most important are the drawing and the value.

Now, as to your question in offering portraits. One can do this when ever one likes but if you wish to be considered as a professional then professional training and study is a must first.

I hope this helps.
