omg, this thing has been totally owning my soul for MONTHS now and I STILL feel like I have so much work *whimper*
(in this situation, one finds oneself asking if it is /really/ worth the trouble....)

...but besides all that.
I'm having all kinds of issues with the daddy wolf's arm. It seems too big and hulkish as is.. and yeah i know werewolves ARE big and hulkish, but it just doesn't seem to work. I have to be careful where I place his hand, because if it covers up too much of the baby's face, that doesn't work either.
Also, what about his fingers? Do they look "werewolfish" enough? Or are they too long and like people fingers with claws?
Do you think the angle of his arm and hand and shoulder are right? Redline, anyone??? o.o

I like the composition except I think it might be a really good idea to add a little extra on the daddy's side.. he feels cut off and a little pushed out of the image.. and besides.. I goofed and wasn't supposed to make the picture square, anyways (was remembering last year)

So the idea is that this family of werewolves are lounging around in the grass on a summer day... I think the puppy is going to be a female and we'll go with a "daddy's girl" sort of theme.
So dad wolf is laying on his belly, mom is sort of on her side with her head propped on her arm, her hand sort of hidden in her long hair...
they /are/ supposed to be on an incline of sorts..
there will be lots of grass/flowers/whatever along the bottom.. will help cover some problem areas ;}
They will have jewelry and possibly tattoos, but that will be done very last.
There will also be a lot of work done with lighting/shading to bring all of them together in the same area.. but usually I try to get my colors, my textures, and everything else done first...

I'm not sure about the mom's long hair... but it's hard to say since it's in such a rough stage.

and yes, the background is a photo. I just stuck it in there because i was tired of looking at the solid grey color that was there before

Okay!! Help!! any comments, critiques, suggestions.. I would be quite thankful! Don't be afraid.. even if it's something I haven't mentioned.. i've been staring at this thing for FAR too long!
