Difficulty drawing black dogs

You've done a pretty fantastic job so far as I can see - dogs move, stretch, hunch .... you don't need to reproduce a photograph exactly; a few moments later and this one could have achieved a quite different position.  Don't worry your picture to death, whatever else you decide to do.  I've drawn a black dog (mostly black) and painted a black cat - as has been said, there are often other colours in the depths and sheen of the hair, browns, deep blues, purples.  If I were going to do any more work on this one though, I wouldn't worry about the colour, and probably wouldn't do anything, but I think the neck length to which Marjorie referred could be corrected by a SLIGHT adjustment to the dog's right shoulder, ie on our left; just a touch, no more. Commissions - I don't much care for them; my dog drawing was a commission, from photographs - absolutely hellishly difficult, but thank God for Mars Lumograph pencils.  I will do them, for lovely money, but it always amazes me how people want a really difficult subject - never something nice and simple...

That’s looking great now Rachel, a really good representation!
