Just give up

I've seen these 'split-face' drawings in the past and I wanted to try drawing one so...here it is! 
Heather and Dom are both fiery-tempered and stubborn, so I thought that they'd be good subjects for this. 
They quickly become best friends during the story (that I've been working on forever, yes I know). 

I also wanted to practice differentiating expressions and facial shapes. I tried to make their angry expressions different (mainly just through mouth shape). Dom's looking down because that's what he spends a lot of time doing (being 7'6''). Heather's 6'1'' but I think she's more likely to be at eye-level with most things.
