The drawings are pretty good overall, but I have a few suggestions on your coloring.
Don't use markers. The color changes from a normal color to a darker one because you overlap your marker lines when coloring. If you use colored pencils instead, the colors will blend nicely snd the art will look much better.
Try to shade your art. Shading makes the drawing, especially the people, much more realistic. If you're not sure how to shade, you could look up tutorials or other sources of information to help you. I know this can be difficult - I am learning how to shade as well. :)
