I just checked out your comic on my iPhone. I like the often-very-simplistic-but-occasionally-complex-drawings-juxtaposed-with-adult-themes aesthetic!
As a phone user, I feel like there's too much going on width-wise. It plays well on my computer screen but I have to hold my phone sideways to make it big enough to read the text, and then it's still too small to enjoy the art as much as I want. I don't think I'd recommend redesigning your style to suit phones though, because it's working pretty well as is.
Oh shit I just reread your post and realized this isn't what you were asking for. Damn, well, maybe it'll be useful anyways!
I'll also say that new readers are lazy and urging them to download something to read your comic might not go so well. But that's just speculation- if you do do it, you should report back here and tell us how it went!
