Thanks!

Try to use the variables you declare in your code, rather than fetching them again.
For example, you set the active document to a variable, but then you use Application.DocumentManager.MdiActiveDocument... to start a transaction. Others may be more willing to look at code that's succinct and doesn't use fully-qualified names
Unless your code is designed to be usable from some other context besides a command, you should use the Document's TransactionManager rather than the Database's TransactionManager. The former will ensure that graphics are updated in all cases, but the latter may not always do that.
