You’re going for this cartoony-semi-realistic style, and it looks very nice! The only things I can really point out is her arm’s anatomy is a bit off, and it looks like you may have gotten a weee but lazy with Sally’s hair. Her arm bends in a very odd way at the forearm, which makes it look like the bone is made of rubber. The hair starts off rather messy, with lots of loose strands, but it smooths out and kinda hides behind the armrest of the...what is that anyhow?

XD that’s all I got. Keep up the good work!

{EDIT}
Also, the man looks like something of an amorphous blob to me. Idk how I’d improve it tbh, I ain’t no artist XD. Ultimately Sally is the focus, so not THAT big of a deal. I will say tho, that his arm is definitely too thin
