You have all Vanguard stock index funds in the form of ETFs, so you did great. The idea of 7% not being a good return is ludicrous. Since you used index funds, you get the average market return. And the average market is NOT just the S&P500, so get that out of your head right now.
The 2014 hotspots were REITs (you have no specific REIT index fund) and US large-caps (you have more than half your portfolio in these). International funds were negative for the year. US small-caps were in the middle.
So I guess I am asking what did you expect?
More feedback: For US equities you have VUG, VTV, VOO, VO and VB in rough proportions that when added together just are the same at Vanguard Total Stock Market Index fund VTI. So why have five separate ETFs when you can have just one?
On the international side, you do use a Total Int'l fund and then overweight int'l small-caps and emerging markets. Nothing wrong with that.
