technical question 2 & moo sketch spoilers

So based on the previous post everyone voted for the original em dash (58% votes), however many in the comments kindly suggested regular font for dialogues and italics for thoughts. And I wondered would it look good? ?

I'm gonna spoiler you with next part sketch preview as an example lol please take a close look at this, which one is readable and understandable as thought vs dialogue?

Personally to me the orginal em dashes kind of ruin the aesthetics of the art but at the same time they highlight the dialogues well ? While I agree regular font is looking nicer, but I only wonder does it show right away that it's a dialogue? I mean I don't want readers to get confused where's the dialogue and where's the thought. Is it contrasting with italic font or not? You can download the image and look at it a few times to see the difference.

this pic in full with regular font if you look closer (oops spoilers ?)

vs the dialogue in italic + punctuation

And if we decide to go for regular font as dialogues, now that I think would it be alright to fully change the text layout like that? Switching layout is a big thing to do, but I'm ready to do this if it's looking aesthetically good, does it?

If you don't know which one then you don't have to vote, vote only for the one you like better. Also you can leave your opinion in the comments and I'll check them, let's discuss, cause before I finish this part and update it I want to improve my story overall ?
