One of the first things I see is the greatly varying color, well done, may I add.
Each of the colored entities gives off a slim amount of light that you can dimly see reflecting off of either Madame Prisme [The assumed main character in this drawing] or the line of bricks, assumably a stone balcony of some sort.
It feels, ambient. And in other places, the mood is confusing.
All the colored entities are smiling in general.
But... [I can't tell if this was done on purpose by the artist or not]
The Red one on the left has the largest grin, while the Purple one on the right has the lesser grin.
In the middle, I can't tell what Madame Prisme is thinking.
Her head is tilted.
Arms are between her lap. [Which could represent many things, from anxiety to depression or maybe even relaxation.]
I become mesmerized every time I look into her eyes, because I can't tell.
The way those... eyes... are separated I could see 4 different expressions.
I'll never know...
It's mysterious, something that i'm looking forward to keep me awake next weekend.
Overall, this is a fantastic work!
Every time I make something, I look back at my work, only to notice the imperfections. But to me, this could hardly get any better.
Good Work and Good Luck!
