It has been a while since I last did any aquarelle paintings and this is the first one I did related to My little Pony.  
In my constant attempts to advertise for my first MLP fanfiction “Lessons in Quirks” (here are links to the story as a PDF File on Deviantart and another to the story loaded on Fimfiction ) I painted another scene from the story.  
This scene is from chapter LXVIII and the depicted excerpt (obviously torn out of context here) reads:  

 
Twilight made a gesture encompassing the whole dark cloudy night sky from which the rain was still pouring. She cast a rather useful little umbrella spell as she stepped from the porch and began to walk in the direction of Golden Oak Library. Celestia and Luna joined her and for a moment Twilight curled her lips at the idea of the unlikely scene of the Princess of the Sun, the Princess of the Night and the Princess of… whatever she was the princess of tramping through the forsaken alleys of nightly Ponyville through torrential rainfall.  
“He would have set up his tent”, Princess Luna said matter of factly. “But he was glad he didn’t have to.”  
Twilight gave her a surprised look.  
“One can see more about a pony if not too dazzled by the light”, Luna said sententiously.  
Celestia raised an eyebrow, giving a taunting look which Twilight was sure she didn’t often display.  
“I’m sure being able to visit that pony’s dreams also helps, my dear sister”, she quipped.  
Luna ignored the quip as she said very seriously: “He didn’t tell us everything.”  
“He did not?” Twilight asked surprised.  

 
It was quite interesting and fun to paint the picture and making sure that in the nightly thunderstorm scenery everything seen through the spheres of the Princess’ “umbrella spells” appears slightly brighter than the rest of the background. I also made a point of making Celestia’s and Luna’s hooves utterly unsoiled (something specifically mentioned with regard to Celestia at one point in the chapter) while Twilight got some mud sticking to her hooves.
