Yes you are off. The first thing you need to work towards is accuracy. Forget the grid method. If you're drawing from a photo, first determine the ratio you are going to draw the picture, for example 4 to 1. Then start with an eye measure it on the paper and draw it. Measure the distance between the eyes then the other eye. You also might want to use a protractor to get the angle of features correct. Once you have accuracy, you need to get rid of the outline. Your shading is not even an attempt to make it like the photos. Finally you have to use a wider range of values. Don't just use a number 2 pencil. You can not pull that off.
