WOMEN

Nice work, beautiful eyes and lips for sure.

I want to show you some links:

There are some pdf's there to look at for some general guides for body drawing.

Also some threads here that have people displaying life drawings and they have the construction lines to show work flow, might give you some ideas on how to avoid the shoulders being too small.

I find that if you use a ruler to keep track of the ratio it is less likely to look off. Also remember to have a break from it and look at it like it was on a wall to really take in what is wrong and right from a distance.

Jam it back in, in the dark.

I don't really mean use exact measurements or draw a grid with it.
Just to help see better for alignments when you get into the trouble areas.

Well some artists draw game character designs up to 9 heads. Just make sure it looks good lol. Especially if they are suppose to be 2 meters tall or something.

There's nowhere I can't reach.

So you should know that the foundations should be perfect before the pretty stuff gets put on the bridge, car, gadget, etc.

Showing reference is a good habit I think, makes you appear more upfront and honest in most other places...especially when you do realistic style.

This thing is sticky, and I don't like it. I don't appreciate it.
