Thank you, Bit! You're modesty and candor speak well for you, but I'll stand by my original appraisal. Tracing is a perfectly legitimate art technique (as an amimation fan, I'm quite familiar with it in the form of rotoscoping). Photos can guide one where to draw, but certainly don't tell which lines to choose. For that, the artist must rely on his own good judgement. This picture doesn't have any "traced" look about it... you've interpreted your source well! I'll certainly look forward to more!
