First reply!
Looks good, certainly better than anything I could draw. But a couple of thoughts...
St Basils is not normally considered a part of the kreml. What you've drawn would be a perfect replica of Red Square, except that there are no buildings in the centre of red square.
The kreml itself (only one edge of which borders red square) does have buildings inside it. There are the official government offices, and in the area accessible by tourists, seven of the most beautiful churches you are ever likely to see.
Plus, St Basils is pretty much a circular structure, not a long one.
Historical point: The kreml was originally built long before communism. At that time, the towers had orthodox crosses on the top, not red stars.
I'd separate this out into St Basils as a happiness wonder, and the kremlin (NOT red square) as a forbidden palace.
ETA:
http://www.moscowkremlin.ru/IE3/english/ has a good amount of detail on the place. If you imagien you are looking at the minimap (clickable) on the front screen, then you are standing in red square. St Basils is on your left, outside the curtain wall that marks the kreml.
