Seeking feedback on Private URL Preview

Hi all, I'm hoping I can get some feedback specifically on font sizes and graphic spacing used in webcomics.

Here's the Private URL Preview (I hope) -

Intro: I'm not new to comics and have worked exclusively on large screen formats for big screen PCs and laptops. I'm entering the small screen scrolling webcomics for the first time. I have tested the Preview on phone device emulations on my browser - results OK. But I don't trust the emulation. I'm chasing feedback of actual experiences from people reading the Preview with real phone screens. Seeking feedback as follows:

1. Font size. Are the fonts used in the preview readable on your phone screen? I'd like to make them smaller if I can. I don't want to go bigger. The bubble font used is 36 pt. If possible, I'd like to go smaller, say 32 -28 pt.

2. Graphic spacing. In this Preview test, I've intentionally placed the graphics as close to each other as I dare to experiment. I'd like to space them with more "air" between them to have a less cluttered feel, but I don't know what phone users are used to when reading webcomics. I have studied some of the popular comics on here and notice some creators use huge spaces between graphics. Is this a sort of requirement for phones, or is it creator style only.

That's about it. I'm not seeking feedback on content, but if you wish to, I'm happy to receive any. Please feel free.

Thanks in anticipation. Regards all.
