Questions in UNDERTALE

Which one of these projects should I focus on and possibly make a trailer for underevent plus this is a reveal for a outertale themed deltarune mod

Which of these Swap Sans do you prefer?

Which one do y'all like better?

Here’s a physical version of a small marketable version of Martlet that I call Smallrtlet now you can easily tell how to make the bead pattern and now for the poll for who from underswap yellow I should make into a marketable bead next

У меня в планах нарисовать персонажей undertale yellow в стиле underfell но вопрос в том есть ли в этом толк ? // I have plans to draw undertale yellow characters in the underfell style, but the question is, is there any point in this? //

Ok I gotta ask: Does Undertale Yellow's Genocide route cause any permanent changes to future runs? I just haven't seen anything about it from just scrolling across sites.
Also if there are don't tell me exactly what, I wanna figure it myself >:)
