punctuation for postpositive descriptive adjectives
Does the following sentence work as-is, or should the comma be either a colon or a dash, or should I just avoid this sentence structure?
"My colleagues appreciate that I am a team player, flexible and always willing to help out."
I do not mean to list 3 attributes (I'm not asking about oxford commas ;) I mean for 'flexible' and 'willing to help out' to describe a team player. An equivalent sentence would be 'He was built like an ox, solid and strong.'
