Seems ok to me, though International % seems high. Im not a huge fan of preferreds as the income source, vs a dividend stock index or more bonds. Preferred have a higher risk level and more correlation with stocks, so they lose some of the returns volatility reduction benefits more bonds bring.
I might increase canada and US % to 25% and decrease international to 10% and drop the preferred index. The stock funds will yield some dividends you can spend. I prefer to think of reits and preferreds as dividend focused stocks, not as bond substitutes.
