Ok, I modified the area a little (temperatures are now a bit less extreme)

I am still hesitant when it comes to lowering the temperatures north of this mountain range - the winds should be blowing from the sea after all. (I'm keeping the winter high because the region feels wrong without it) And while we're at it: if the winds are blowing from land through that southern sea will they bring rainfall to the equatorial contnent? The closest comparison is probably the red sea, so the answer would be "no", but it isn't perfect match (I kinda need it to rain there)
