My current problem on drawing & April plan

Hey guys! Thank you for another month of support! I wanna apologize for not giving an update for 2 weeks. I know you guys have patience but I just wish I could provide content more often. Sadly I keep failing to do so and I think it's time to address the trouble I'm facing to you guys. Some advice will be nice, and if not, at least you guys can know my struggling situation.

Long story short, once a piece reached 50~70% progress, I started to lose interest in it. I'd look at it half finished and start to feel like "This one doesn't look good so far, and it's gonna be disappointing when it's finished". As the result, I'd waste more time on it, adding more detail, changing the background, struggling with making any progress. It become more and more stale as I did so and it always ended up taking super extra time for one piece to be finished when it didn't have to in the first place. 

For example, I was planning to finish my Twilight doodle in 2~3 days. I was only aiming for a rough doodle without excellent details so 2~3 days is a reasonable, at least that's what I thought. Yet, it still turned out to take me 2 weeks yet nothing impressive had come out. I kept redrawing the clothes, lines, colors, trying different angles and still couldn't find the right path which leaded to a "finished version".

It's basically the general struggle I have to all my work. As the graph shows (See the graph down below), once the progress reach 70% or so, I lost all the speed, motivation and vision to progress toward the end.

So this is the problem I'm facing now. I hope I explained it well enough. In order to fix it, my plan/goal in April will be "Finish things in 4 days no matter how shitty they might end up being." The quality of my art might be way lower, but I hope you guys join this experiment with me . I noticed some artists didn't make the finest art but they update regularly and consistently,  and they still got great support, which is my goal now.

Also in April I wanna finish these things.

2~3 OC doodles. (I already got the idea)
1 poll result
1 Sr
Twilight doodle

And I wanna say I'll finish the pinkie twerking animation but I'm afraid to promise that, so we'll see.

I hope this post explain the bad situation of mine well. I welcome all kind of suggestion and advice! Leave it in the comments if you have any! Thank you so much!
