If you want to make a digital version, you should look into either inkscape (like illustrator) or GIMP (like photoshop). Both of these are free, and a simple google search should bring you to the download link.
As for your 2 newest pictures, they look worlds beyond what I could do. Then again, I have yet to practice proper anatomy. One thing that I do notice is that the first female has odd looking fingers, and they don't appear to have joints. It looks like you took your time with her body, limbs, and head, but then rushed the hands. As for the second female, I can tell you went into a more cartoon-like anatomy either from the time constraint (you said you rushed it), or personal preference. Either way, that picture could probably use some joints in the arms even though it is more of a cartoon person than a realistic person. I also assume you meant to add the eyelashes that are the size of bird wings to her face. Who knows, maybe she uses them to fly around.
Keep up the good work.
Also, I really like the picture of link, but I do wonder where the pig even came from if he is on a small platform over what appears to be water...
