hii!!!! it depends! For the ychs they take not super long, max like 30 mins usually since i make the base + animations beforehand and just have to swap the symbols. The bases themselves usually take much longer depending on my idea / making the animation look right though i've never timed myself pff

For bigger ms paint pieces i think max like??? an hour and a half :) I usually draw all at once and I'm very very fast ngl LOL i have had people comment on how fast I am at drawing while they watch me do it
