dont worry about people who unfollowed you. You have a very unique art style and should not get your mood dragged down by something like that :)
If you are ok with some advice/request thing, i would love to ask you to do some more artworks with backgrounds and try more character poses. Try drawing them while sitting, running, jumping and interact more with their surroundings! (just like your gorgeous profile pic) This makes pictures more interesting to look at and will get your lost follower back in no time :3
on the other hand, trying out new things that you arent comfortable with, will help you improve! :) You have such a great potencial and i really wanna see your art improve :O
sorry for the stupid life advice, i hope this was helpful :)
if it wasnt..uhh just ignore this comment and I´m sorry for making your read this novel like message :D
