Thanks for posting the ref.
You cant expect to learn much if you have to resort to tracing reference. If you cant establish the shapes, proportions, and proper anatomy by drawing from observing reference, not tracing it, you are not going to be able to light model, shade and color the work properly either. One of the reasons the face looks distorted, is because you distorted the ref and used it as a guide. You vertically reduced the ref photo, or your tracing, to 85% resulting in a squashed version of the original.
Youve got to learn how to draw first, and build your image from the ground up, on your own without the crutch of tracing.
The attached image shows a traced version (A) of the original ref, and (B) the squashed version of it that happens to fit your work like a glove.
