Starting off I think that this is a cute, well drawn commish that sleeptofade is lucky to have.
The idea that must have influenced this is awesome, but I love the overall color, shading, and highlights put into this. Fluttershy's armor really brings out the... what's the word... childish way of having a pillow fort.
The socks scattered around the fort bring in the flags from a real fort. I find this very cute. The doll is awesome. The button eyes and the sock hair! (It's supposed to be a sock that fell on the plush's head, correct?)
You have seemed to put a great amount of time, highlights, and shading in perfecting the idea that brought this to life. I found this very enjoyable to look at. I found a sense of humor in it, and I just love the overall picture. It's happy, sweet, and I love it!
This has to be one of the cutest things that I have ever seen in my life! First of all, I love the way that you used the environmental details to your advantage to make the piece far more playful! Such as the strainer on her head that covers her eyes as well as the random sock that hangs over the side of the tent! The character design is lovely and I love your use of soft textures! The color work is very light, but it contrasts extremely well with the lighting and shading! Overall this is a really great piece and I would love to see more! Great work! Kind regards, Princess Luna
