You wont have to start again as the make up will hide most of the flesh. If you wanted to trying and change it and add a little depth, mix up another flesh tone but much more on the white side, almost white and add it as a wash. Only add it to the areas where light is most likely to catch and use your finger to dab it in, small sections at a time. I would then mix up some blue, red, purple, light brown and dark brown and flick the paint in. Start with blue, dab it in, then red and so on. You do not want prominent spots or flecks. Once you have done that, add another light, diluted skin tone over the top so all that detail you have applied will sit underneath.
Also dont make the eyes to white as they can look goggled eyed and cartoon ish. Add a very small amount of yellow just so its slightly off white.
Another thing with the eyes, they are a real pain to get right and very much a focal point. Id consider buying some of hunters 1/6 decals . Its alot easier and a lot less nerve racking lol.
there is no right or wrong way. Just have fun and keep tweaking until you are happy
