What!? How could you forget!?
Nah, I'm kidding, I've made mistakes like that before. I once did an art of Tails from the Sonic series...without his iconic tails T_T I realised it pretty quickly but still...

I forgot tails on anthros all the time, lol. I've been a little better about it lately, but i'll draw a character and stuff, then be like "crap, I have to add a tail in". :P

Yeah, I normally leave tails until last, even though my normal policy is to do basic structure first then add detail to certain areas. Come to think of it, I've been deviating from that policy a lot lately. But yeah, I'm terrible when it comes to tails and some other details of art, especially getting the light and shadows right. I'll spend a lot of time on the subtle and not-so subtle changes in light on certain parts of the character but forget to do overall lighting/shadows for the character and the scene >.<

this is so cute.
