先週私へ郵便局いきましたそして手紙をだした。
Senshuu watashi e yuubinkyoku ikimashita soshite tegami o dashita.

I'm not sure if this is right, but I tried, right? ^^;
Anywho, I pass on...花鳥画 = かちょうが (Kachouga) which is a noun, and means the painting of flowers and birds. I'd like to see a creative sentence for this one.
