Is there a Guide on how to draw Hybrids?

Or someone who is willing to draw one (which I doubt)?

I have an idea, and I basically thought it would be cool to have a horse with spider legs, along with a few other demonic looking things to it.

But I don't know how to draw a spider or a horse, much less the two together.

I'm not sure that such a guide would be able to cover all hybrids. At most, you'd think it would cover the more common things like centaurs, griffins, etc.

I'm not sure a horse with spider legs would work that well... there doesn't seem to be anywhere for the extra legs to attach to, you know?

Maybe you should just start really loosely sketching various ways spider and horse could be combined.

Look up how to draw horses. Then how to draw spiders. Then mix up the steps.
