I see nothing but success all round.
As a portrait, you've captured the subject in how he wants to be seen.
Mark's character performance of Bob Down is Over Exagerated, Over Ego'd not a hair out of place over done variety performer. Its ment to take the P!$$ out of the industry that created the image.
I feel you've accomplished this with your protrait of him.
To quote from an interview of Mark Trevorrow by Jack Marx -
When I reveal to Mark Trevorrow that his alter-ego, Bob Downe, annoys the hell out of me, he emits a theatrical sort of laugh - a descending "ha, ha, ha!" that says both "mission accomplished" and "I know what you mean", with just a touch of "up yours, buddy".
So comments here of "being shot with the wrong device" also indicates that as a performing artist Mark has been successful as this character.
As a performer he is there to entertain. As an entertainer, there are times that playing bad characters are entertaining, after all Monty Python said they didnt try to get a laugh, they tried to shock & people laughed.
Also from this interview (just to prove theres more to Mark)-
In person, Trevorrow has none of Downe's flap and dither. He's sharp with a low-watt eloquence and a brisk, no-nonsense air, as if Bob's blown the budget on the end-of-year party and left his teacher to clean up before school starts again.
So Well done Methd and well done Mark
