Is it permissible to create comic strips using photographic images of real people, with changes in colors and lines to make them appear hand-drawn, instead of drawing animate beings?

The basic ruling is the prohibition of drawing images of animate beings that are complete in their creation. However, it is permissible to draw and produce purposeful cartoons and beneficial illustrated stories for children to educate and entertain them. If the illustrated stories produced by the questioner fall under this category, then there is no harm in them, whether he draws them himself or modifies images drawn by others.
