Which is a correction for the punctuation in the sentence He is a great singer not to mention his amazing dancing skills but I wouldn't call him a talented actor

Period.

Explanation:

There should be a comma before 'but I wouldn't call him a talented actor.' To end the sentence I would use a period since it's more of an opinion/statment not a question or an exclamation such as "Wow!" or "Ouch!". Also a possible comma after 'He is a great singer'.
