What is your investment horizon? When do you plan to retire?
35% is a metric f-ton of bonds and explains your very low return over a period when stocks have been kicking ass. But you cannot go back in time...
I don't think you know why you are invested in these funds, other than a survey told you to invest in them. You're also overweighted in international, did you do so intentionally? Also Vanguard Value Index is a subset of the 500 Index, so these are all thrown together.
If you don't want to get into the weeds on deciding which funds you want, use Vanguard Total Market Index / Admiral, the broadest US market index, for your US portion and Vanguard Total International Stock Index for your international exposure.
If you'd prefer to analyze this a bit, you could do some proportions of 500 Index, Mid Cap and Small Cap (if you want to overweight the smaller end of the scale), and keep the Developed Market and Emerging Market international exposure. Any particular reason why you're in the Real Estate one?
