Been meaning to finish this for some time, but I've been waiting for a bit because I needed to get a new graphics tablet.
Anyhow this is a coloured up version of this sketch [link] which I did for because a) I love his askblinddash blog and b) it was their birthday.
Basically Twilight feels bad about the whole fact that Dash is on a leash so she tries to even it out by wearing her own collar for Dash with a bell so she can hear where she is. Also yet again I recommend you check out the blog because of reasons askblinddash.tumblr.com.
