I like the overall layout of the continent; it seems 'natural'. Like SG, I think the changeover from glacier to grassland is a bit forced. (If that IS a glacier - I wasn't quite sure. If it is a glacier, you might consider breaking up its straight edge a bit more; if you look at maps of projected routes of real glaciers, their leading edges aren't straight lines; parts of the glacier will travel faster than other parts, leaving a sort of rippled-curtain effect.)
