Artwork has improved... Perspective distancing needs work, since it looks like Renko could be scaled down, considering how close she is to the window.
Say, have you tried photoshop before or any other program that allows scaling multiple pictures? I could understand if you can't make changes if this is hand-drawn, but if this is computerized drawing, then you should be able to shrink or expand the size of people down to their proper sizes on a case-by-case basis.
