I have found two map that might help you :

to sum up, I think your altitude map make sense. One thing that would be nice is if the zones could have a different width and maximum altitude ( alittle bit more of variation). For example of what I mean, just look at South and North America. The mountain zone in the south is higher but thiner.

About the temperature map : It look ok but since climate is different even at the same latitude (I bet you don't even have snow right now in the UK) it's hard to judge right now.
