Editing advice: don't put spoken dialogue vertically. It can be reeeeally hard to read. It's fine for SFX, though.
Ex: Page 15: The "thumps" are fine, but "then..." should be horizontal, even if it cuts across the bubble. Sometimes you'll have to put them on two different lines to make it fit, like:
Basically, Lusamine got all coocoo after losing her husband and finding a fascination in the Ultra Beasts. I think this is meant to be around that time, but it really doesn't explain much when comparing it to the main story.
Then again, it's a doujin, meant for fun. I think the big part is just playing into Lusa's crazy personality.
Man these Lusamine x guzma doujins suck biblical levels of dick, i just want to jerk off to Lusamine's delicious design and not think: "If i click next page , am i going to get more of her or it will be a dumb reaction panel from this idiot?", sigh.
