Art Fight has posted about their mini event called art Fright! 

If you participate before November first you can get an achievement on the art fight site (there is a Google document link on the tumblr post I will be linking for that)

If you don't plan on getting that achievement on their site you can get an achievement here if you draw any crithit characters with the prompts or color schemes.  Add your submission to the shards prompt and gallery you can then link your gallery submission in a claim and ask for the Art Fright Achievement. 

Be sure to mention what prompt and or color palette you use in the submission. 

You can do it more that once, only once, or not at all. Totally up to you!

Here is a link to Tumblr for more information 

NOTE CRITHIT IS NOT AFFILIATED WITH ART FIGHT I JUST THOUGHT THIS WOULD BE A FUN IDEA!!!!!!
