Design experiments

Here are some of the sketches that I've been doing for this comic project that I rolled the dice for. If you don't know what I'm talking about, watch this: [link]

There are a lot of challenges associated with making humanoid/dinosaur characters that have any kind of comprehensive design and are appealing. I definitely don't want to just stick a dinosaur head on a human body.

A couple of questions for you guys: Which designs do you find most appealing? Is there something here you'd like to see more of, or perhaps some other art that you think might be inspirational?

These designs are based on raptors. Do you think I should use other dinosaurs?

What days do you like people to update on? I've been doing Saturdays, is that good for you?

Anything you can tell me would be REALLY helpful.
