Thank you so much !
I don’t master watercolors myself so I’m at a loss what to tell you that could be useful… er let’s see, I always work from light colors to darker colors, I build up the shadows little by little. I let my base colors dry first and when I add shadows I use clear water to blend the edges and make them smooth. To make shadows don’t necessarily use a darker shade of your color, try using purples, blues, reds, etc. Never black !
To keep areas white I use masking tape too, it’s really useful. Other than that be sure to always have clear water and tissue available, and always test your colors on another paper first to avoid mistakes. And also, don’t give up ! Watercolors are hard but they’re really fun and after a while you’ll be glad you hung in there :)
If you browse websites like Deviant Art you can find many tutorials. Do try looking at Goldseven’s work, and also Aurora Wienhold’s gallery, because they are masters. There’s also this AMAZING tutorial by Claparo Sans, who is mindblowing at watercolors ! http://claparo-sans.deviantart.com/art/Watercolor-Tutorial-122714589
Good luck !
You’re totally right, I had given her more of a copper skin tone at first like in the movie, but then as I added lights and shaded the color darkened and I didn’t notice before it was already posted-__-
