After looking through your thread I can see a marked improvement over the years! Good job!
I do have some suggestions about the Ruby and Chomper picture, if you don't mind me saying:
I think that if you drew Chomper smaller and had him sitting more on Ruby's
chest than her stomach the picture wouldn't be interpreted as being "questionable". I didn't see it that way on my first glance, but I can understand why it is viewed that way.
Also, on your most recent picture, the only thing I would say to improve upon it would be to redraw the outlines to be thicker, but since you said that the full-sized versions were lost I guess you can't work on it anymore.
I hope I don't come off as too caustic :unsure: but I do like to critique art (in a constructive way).
