Can't argue with the consensus here: this is Adorable with a capital A. <3
The simplicity of the design belies its endearing charisma: there's a lot of charm and personality to Sal's long hair and casual clothing. The rich, warm colors you use certainly help in that regard. As well, that stern but gentle pose and that kind but impatient expression paint a very vivid picture of what this Sally is like.
I figure Sally to be the casual type. She doesn't do accessories XD
As much as I love her 'short hair', in the comic I hope to be making soon she'll be the type who isn't one for keeping up appearances i.e. getting a trim every now and then but makes up for it by being naturally pretty anyway
