Comment/critique themed Art challenge?

I have this idea for a while now and I wanted to know what you think about it:
It will be something for the Emoticon community but everybody else is welcome to share their opinion.

My idea:
I will give you 2 themes (or Art prompts), then you can decided if you want to participate or not.
There will be 3 lists (beginner, advanced, mixed) each deviant will get a number and a randomizer will decided who will work "together".
If you decide to take part you will have to pick one theme/art prompt then you will have 1 month (not sure about that yet) to create the piece, after that you send the link of your deviation to your partner.
Then they have some time to write an in-depth comment for the piece (tell them what you like about the piece, what you don't like, what do you think of their colour choice, how well did they incorporate the theme . etc.) Don't just say it's awesome or I like it, that's not the goal of the challenge.
The goal is to create Art and to write in-depth comments and of course to improve you Art.
I will also write comments/critiques for the pieces.

I thought it would be nice to not just give themes (like "pirates"), I would describe what should be included like "tree-house, balloon and zombie". You would have to decide how you want to draw it. (or I will describe the scene like "Portray a sense of pain with a buried treasure and a mask". From the random art prompt generator )
And everybody can suggest themes/Art prompts.

I had this idea when I found the Random Art Prompt Generator

What do you think about it?
