Of all the artworks I have commissioned with my dragon characters, I never actually purchased a painting of a sleeping dragon. It is such a simple, perhaps even boring pose, but I personally find it very serene. Dragons are naturally proud and powerful creatures, but when they sleep, they end up looking super cute and pet-able, right?
The added bonus for Rynthara is that she is a very photogenic dragoness, so this pose really ups her cute and cuddly characteristics. So long as you are not around when she wakes up, you are free to admire her tranquil form :P
