I was commissioned by a good friend to do a family portrait for a Christmas gift to his wife. I originally had some problems getting the children to look like children and not little adults. With the help of my Creative Cup critique friends, I got some pointers to youngen the youngsters:
1.) Big heads, narrow shoulders
2.) Eyes dropped down, make wider apart, and a bit smaller
3.) Big cheeks, big forehead, narrow chin!
4.) shorten the nose
I know it seems like a recipe for drawing an alien...but when you're done, it looks like a kid! I matted it, framed it, and now it's ready to go under their Christmas tree!
