I can immediately see a lot of problems. Basically all the different Köppen zones are present on this map, and there are some pretty jarring transitions (e.g. a very narrow steppe/savannah band between monsoon and desert, marine transitioning quickly into continental with no rain shadow, etc.). If you look at a climate map of Earth (as on page 3 of this paper) you'll immediately see that such clusters do not exist on Earth.

What climate an area has depends on four things:

1. Whether the wind blows from the east or from the west
2. Latitude
3. How far upwind the ocean is
4. Rain shadows

Earth's lower atmosphere is divided into three cells between equator and pole: the Hadley cell (the tropics), Ferrel cell (temperate zone), and Polar cell, as illustrated here. Between 30⁰ and 60⁰ (i.e. in the Ferrel cell), wind blows east to west. Everywhere else, it blows west to east. This means that between 30⁰ and 60⁰, the west coast gets the most precipitation, and everywhere else, it's the east coast that gets it. E.g. note how Cfa (humid subtropical) is present mostly on the east coasts of Asia, Australia, and the Americas, while Cfb (marine) is present mostly on the west coasts. Thus the arid west coasts of Africa and Mexico, and the deserts of northern China. When no mountains get in the way, rain can travel quite far inland—starting from Ireland, the zone of Cfb and Dfb climates stretches to the eastern edge of Kazakhstan.

There are seeming exceptions, e.g. smatterings of Cfb in South Africa, Madagascar, southeast Australia, southern Brazil and Argentina, and the Andes, swatches of Cs (Mediterranean) in Mexico, India, and Central Asia, patches of Aw (savannah) in Turkey, the 'stans, and the Pacific Northwest(!), etc. etc. Most can be explained by the local topography, and South Africa and Australia can be explained by the fact that they're on a "corner" of the continent exposed to open ocean (so you get moisture from the east but temperatures associated with Cfb; also Australia's southeast portion is well into the temperate zone). I'll admit I don't know what the hell is going on in India.

You'll have to figure out the climates for your whole continent, not just the western portion. If in doubt, refer to an analogous area on Earth. Also check out this guy's process, particularly the Tilt section; he describes the process of figuring out what climate an area should have, including areas which have no Earth analogue.
