The precipitation map doesn't seem very realistic.
It is hard to comment on climate when latitudes are not shown. I suppose that you had them but then forgot to show them on your maps. So my comments stay rather general.

What is immediately striking is that your precipitation maps show a circular symetry on continents.
This never happens. On the contrary the atmospheric circulation is always asymmetric and depends on latitude - it is either the westerlies or the easterlies that dominate.
For example if your planet rotates like the Earth then you'll have dominating westerlies in the temperate northern zone. From that follows that the western edges of continents will be much wetter than eastern edges.
This asymmetry is especially important if there are N/S mountain ranges. These will create a very strong rain shadow on the eastern side and very high precipitations on the western side (think Vancouver climate which is defined by that dynamics).

For the temperatures.
T depends on altitude in a pretty linear way - on the Earth it is in average about - 7°C/km . A bit more if air is very dry and a bit less when air is very humid.
That means that a 5 k high mountain in tropics will have 30 °C at foot and - 5°C on the summit. This difference will stay the same in winter and in summer.
Also, on the contrary to precipitations, the temperature distribution is more regular and symmetric. Temperature is basically distributed in latitudinal bands (e.g the average temperature only depends on latitude) with a large discontinuity between oceans and continents.
This is due to the fact that the amplitude of oceanic temperature variations is much smaller than the ampltude of continental variations. It is this difference which creates seasonnal monsoon regimes on approppriate places.
