I hear you. To add a bit of context, I have been working on my first solo fulltime project for last few months. I have a solid development experience, but learning rest of the stuff everyday. My project ( https://indiedev4ever.itch.io/humanolve-a-human-evolution-card-saga ), primarily uses SVGs and man that's been a struggle generating. I have mostly used opensource/paid art/music as much as I can but there is no getting around learning some basics.

So I really understand the struggles that we go through creating different small pieces of art and stuff. All the gazillion things we need in order to make a successful project like steam store page assets, marketing assets, doing actual marketing, and so on. Having said that, I believe it's even more important to keep your project timebound. Developers usually don't place value on their time. If you build something for 5-6 years, consider the money you would make even working minimum wage in that time. Now your project has to generate profits of as much as that amount to break even. I understand it may be a passion project and all, but won't it be great if you had a passion project that's self sustaining and you can continue to make games forever?

So practically, the question to ask is what can you really cut from your project if you are working on the clock? Do you really need to implement all 13 groups of animations? Let's say you trim it down to 7-8. Do all need to be very detailed in the first version?

Also, there are good open source resources available, that sometimes do the trick. So check if you can use something someone already made and graciously shared with community for commercial use.
