**Short answer:**

Equatorial regions: [temperate rainforest][1] 

Polar regions: [tundra][2]

**Long answer:**

I assume that if you made such elaborate question, then you expect something more. ;)

Thus:

1) I have mixed feelings about this climate on South Pole. I understand axial tilt and so on, but on our warmer planet, on Vostok Station the average annual temperature is [-55C][3]. 

2) Such longer seasons make animal migration much more viable strategy than on Earth. Thus big part of fauna should move with seasons.

3) Longer vegetation season and longer winters makes slightly favours single year plants. 

4) You don't have 4 seasons. Seasons are arbitrary distinction created by local civilisation. Your civilisation lives in tropical region, where what matters is rain season and dry season. Because of higher axial tilt and imbalanced land mass such pattern should also more or less apply to equatorial region.


5) With such size of star, it should stay in main sequence for 5.7 bln years. Seems OK, until you include that the star luminosity increases even when its in main sequence. Thus a if right now the planet is so cold, then a bilion years earlier it should have been a snow ball. (yes, workable, but it would require some explanation like orbit migration or much higher CO2 content in the past.)
