No not the Pratzen heights, its the northern area of the battlefield where the bigger cavalry clashes took place. Are the Czech maps you used online available?
I'm not so much worried about the villages but from various descriptions of the battle in that area and from some maps I point out 3 things:
1. The massive forest in the north might not nearly have gone that far south.
It's often mentioned that Bagration was in a line north of the Brünn-Olmütz road, but that would mean he would have the forest in his back or would even stand right in it, such a position was rather unusual as it denied a possible retreat. It's also mentioned that Bagration tried to go around the French left, for that he would have had to go even further north than he was positioned already.
Some sources also mention a previous position of Bagration in the very early morning that had his line running north almost on the hight of Kowalowitz.
And in the afternoon there is Russian cavalry north of Kowalowitz, what again looks strange if so much forest would have been there.
If the sources are correct it seems to me that the forest edge should not run that far south, especially not on the hill at 190,16.
2. The orchard/forrest hexes between Blasowitz & Krug might not have been that extensive.
A lot cavalry action is mentioned in the area between the villages of Blasowitz & Krug.
But looking at the map, the area between these to villages is shortened to about 1/3 because of all the forest and orchard hexes. If they were so prominent in the area I guess they would have been mentioned somewhere but I couldn't find any mentioning of them anywhere.
3. The Hedge at the big field East of Blasowitz might not have been that extensive.
The Hedge is another big obstacle for all cavalry, but Lichtenstein's cavalry advanced through that area and nothing of such an obstacle is mentioned anywhere. That makes me doubt that it played a role and by that should likely be removed or at least thinned out.
I have made a graphic to show some of the things I mentioned.(Ignore the French line, it's for the #22H. The Battle of Austerlitz scenario thread)
