I drew this on Christmas Eve (lol, obvious) and should've been uploaded sooner, but yeah, it's late.
Anyway, sweet Hime-chan's sharing her scarf with the shy Ishida-kun! Their outfits are a bit inspired from reading Sherlock Holmes (Haha~ I JUST LOVE DOYLE'S STORIES ) and I hope the background is okay. Even though it really sucks.
A little something for the IshiHime shippers for Christmas!
Okay I'll offer a critique since you asked for one, and I find that it's helpful to have people tell you what works and what doesn't.
You're really good and I especially like your coloring style. The hands though are a bit small(I know drawing hands are difficult) I'm sure if you spent a little time studying hands you could get better really fast as you seem to have a good understanding of the other proportions of the body.
Also you might want to move the noses down just a bit as the look a little high on the faces, in particular Orihime's. Also for Uryu you want to try to make the jaw more apparent as it looks like it is riding int the ear. Also this is just a suggestion, you could try making Orihime a bit more curvy, as she looks more slim in your piece than in Kubo's art. But you can always draw her the way you want, it is your artwork.
I hope I could be helpful, I've only really started to try to learn drawing with the basics a month ago so I don't know how much help I can be for you. Overall I think its a stunning piece with just a little bit of tweaking it would be even better. Keep up the good work ^_^
