rough drafts of Mistress Vine, Nezumi ko

Ok i am a fairly new at drawing so don't be expecting wonderious things and these are just drafts. They also look a lot better on real paper. Ok according to the book (yep i am that new) the next step is inking. Err, Problem How do you ink something like this without any way of erasing your mistakes?

Mistress Vine

Also comments of any kind are welcome.

Just getting home to see this. I think you're starting out well. The only big problem I notice with Vine is along her hip/upper thigh area. With the indentation, it kinda looks like her butt is in front. Otherwise I think it looks pretty good. Looking forward to seeing the next step.

As far as the inking questin, I'm afraid I'm no help there. But I'm sure someone will be along who can help.
