Portrait painting

This is my newest oil Painting on canvas.
The size is about 60 x 80 cm, this time I decided to use oil paint in stead of the the acrylic paint. In the course of this realistic painting, some Ideas came in which made the work easier. When ever a painter gets a good sketch for his work he or she won't fine it difficult to get the resemblance of the image been use. In the reverse when one has a bad draughtsmanship he fines it so difficult to get a good resemblance. Moreover, it's good to spend more time in sketching before proper paintings or the laying of colours.
Thank you for your time.
