I'd like portraits to be mostly about showing the unit's face, with their facial expressions. Also, I find portraits are a bit too big and invasive.

Portrait area: I would prefer if there was a frame around the unit and a background.

I'm not a big fan of the new UI aesthetics, but I like that its size has been reduced, it provides a better view of the field, and it gives room for further modifications (I'm still hoping for a wider unit selection and more slots for buttons and inventory!).

I'll give it a shot myself, feel free to follow along. Let's try to be as specific and constructive as possible, not just deliver only vague and general opinions. I suggest we discuss visual changes in this thread: graphics, design and UI, which are the biggest changes so far.

They expect us to provide feedback, and hopefully Blizzard will heed our call! (Inviting you here, if you don't mind) What matters now is that the final product is still a work in progress and Blizzard employees stated several times they were going to have a lot of discussion with the community. So there has been a lot of discussion about Reforged already, with a great deal of hype and hopes, but also questions, concerns and speculation.
