With a starting SG of 1.070, you will wind up with a final ABV of about 10%. That is on the low side, but not unreasonable for a wine. If you wished to have higher ABV than that, you could have added sugar earlier. However, I would not advise you to add sugar now. There is too much danger of the fermentation not kicking off again, and then you are stuck with an overly sweet wine. Moreover, this is evidently your first attempt, so I would keep things simple.
The pink-instead-of-red problem is probably just from light scattering off of suspended particles. As the wine clears, it will darken.
