No, it should not be an issue, countries do not care where you come from.
The important things are that:
- You stay within the dates of validity of the visa
- The duration of your stay is similar to what you originally indicated, and of course within the limit set by the visa
- The reason for your stay remains the same, at least remains in the scope of the visa.
- You do have a flight out of the Schengen Area booked
