Good! Only a few small errors. A few notes:

-In English it is far more common to use the simple past tense. These sentences sound slightly contrived because you have used a different tense. Let me explain:

-Our colleagues <em>were playing</em> / our colleagues <em>played</em>

-We <em>were sitting</em> / we <em>sat</em>

-We <em>were having</em> / we <em>had</em>

-When you start a sentence with an adverb of time then you should use a comma after it
