crits wanted on WIP

Hey, about to start on the hair tomorrow, any suggestions before i start?
things im aware of:

.little sss and colour variation on ear(this will be mostly covered by hair)

.glasses handle going into head

.clothing is not the best by far, its my first time doing any cloth or clothing. any links to good resources for getting realistic clothing with texturing and or creation would be great! (tutorials don’t have to be software specific anything will do)
