Hi Brian ,
Im happy my SBS was of use to you ,and its great to see you having a go
For a first attempt ,I think it looks great . Its hard to judge exactly how the highlights & shadows look until it dries ,maybe then you can push them a little further . The oils look very greasy ,did you let them breath for a while on cardboard or paper ? ,maybe its just because they are still wet .
Anyhoo ,its a great first go and you're on the right road .Please feel free to ask at anytime 
Chris.
