I love what you're doing. Children pick up a great deal of attitude from their parents in their early years, so if you're putting more emphasis on "real" beauty, inward and outward, your children will tend to find those things important. So congratulations on doing this so consciously.
Another source of understanding beauty is noticing and appreciating the beauty of the natural world, the sky and land and water and light, the movement of seasons, wind and weather, growth cycles. This is another area you can culture by choice. Much of the media stops noticing beauty where the body ends, and this is just too narrow. A quiet appreciation of nature gives children a much calmer, more centered place from which to respond to the pressures of life.
Wishing you the best.
