Well, Austria's Burgundian possession should be reduced to Burgundy (which would mean something like: Belgium, Luxemburg, Franche-Comté and Alsace. Something like that. The rest could be made into new member-states of the HRE.)
Now the "German Partition" of the Ottomans should be reduced IMO. You could create a greater Armenia, Kurdistan and Trebizond (

) from it at least. Also, why do the Brits have the Byzantine Empire in that map?
EDIT: also, as above poster has said: there is nothing for the UK to "reclaim" in the USA.
EDIT2: Also, why are the borders in Poland the post-napoleonic one? The Austrian and Prussian part used to be bigger, you know.
