I've bought a couple adoptable eggs, one turned out superb by secretaryrappel (Sundaze the dessert goat) and the other I'm still waiting on now for 3 weeks but I won't shame them here.
I love looking for cute chibi YCHs but some of them are a little out of my price range... (US$125?! does it toast my bread or give me foot massages too?)

I want to know what you all use to do your colouring and linework. Do you recommend Krita or some other freeware program? (personally, I have clipstudios but I don't seem to pull off the same results as others do in procreate and I don't have an iPad)
Do you use vectors to get your linework so perfect?
I don't mean to be terribly invasive with all the questioning, but I'm curious how do you people manage to create and sell such adorable critters?
