Shape looks as good as good to go, but about your placement of elevations and the "tectonic thingy": the two margins of that "new sea" should fit more, both in terms of shape and in terms of mountains (main point is that those mountains on the NW corner of the southern continent could well be prolonged into the SW corner of the northern one - just below the word "grass").

Also, placing all biomes from snow/ice to desert on a map like this will create a huge scale. Why don't you try to superimpose your draft on a map of Earth, aligning your biomes with similar regions - like Sweden to Sahara or Alberta to Mexico to see what I mean.
