You've got a good sense of composition in your drawing, althought the characters lack a bit of composition and proper structure.
Especially on the chin feature of your adult version of Rydia where it expands too much. If you wanted to make it look as if she was looking upward, you should have had a line of determination connecting the neck to the chin. Try looking in the mirror to see what I mean.

Your coloring is good, but it seems that you have more then one light source? Because the two characters seems to be the contraire in the light shading as well as the shadows.

Keep up the good work.
(Sorry if you didn't like constructive critisism, I am an art teacher and I can't resist to be like that when I look at art...)
