Welcome!
Good start. The only thing is i can't tell if she is good or evil. I'll befriend her :^)
Also, her horse is small and cute, i like this.
To answer your question, keep your sketches in your thread and put your 2048*2048 sheet + final illustration in your first post. If you need, there is more informations in the guidelines and FAQ.
Really love her attitude And the bats as well! I do believe that her right arm (for us on the left side of the image) is either a tad to short, or the foreshortening perspective is off (which could be a result of the spiraled leather strips just pointing downwards and not forwards) But keep up the good work!
