I think you're on the right track. Keep learning about makeup and hair looks. I like your eyes. You could stand to accentuate them better, I think. A few lessons in contouring can minimize the appearance of nose width.
Your forehead looks rather low in that picture. If you're wearing a wig, you may need to wear the hairline a bit higher. Your face type is such that your cheeks tend appear wider in relation to your forehead. This can easily be countered with the right hair/wig style. Generally, I think, you probably want a bit more height and width above the eyes, but no width at the cheek level.
Upload the photo to one of the virtual makeover sites like Instyle's or Mary Kay's. This is a quick way to try on a bunch of different hairstyles and makeup looks. The best thing for a wig wearer is to see a good wig stylist and have the wig styled to suit your face-- or, perhaps purchase a different wig. Sometimes hair with highlights or of a lighter color can compensate for certain face issues. I've lately decided that's the case with myself.
