A beginner's ETF portfolio

[loosbastard]

As said above, I'm pretty much a novice when it comes to investing.

20% Vanguard Growth ETF
20% Vanguard Value ETF
15% Vanguard Small Cap ETF
15% Vanguard Europe Pacific ETF
15% Schwab Short-Term Bond Fund
15% Schwab Total Bond Fund

My main objective was a simple, low-maintenance, low-cost base portfolio. I plan on playing w/ some sector ETFs once I get a better feel for how everything works. Any suggestions/opinions? Am I totally lost...or does this look like a decent start?
