Perfectly drawn. Maybe the sizes of the characters could be more consistent. I remember Mojo being bigger than the girls, but it's been a long time so I could be wrong.
Good stuff, you don't need to use pre-zoomed images on PJ.
It would be better if you switch this one with the original res file.
I like how you did the professor, mayor, and villains ^^
They look really cute with that style, especially the rich girl (I forget her name lol)
