Welcome to the forums!
While I admittedly am not an artist myself (by any means of the stretch
) you could try and peruse the following forum threads to hear from what other people advised beginners to do concerning honing their individual art/drawing skills.

https://f95zone.to/threads/renpy-beginner-questions.18675/
In addition, there is the '
Artwork' sub-forum where I am sure others would be happy to provide you with some pointers on how to start your artistic journey in modelling games based on the thematic art style of games that you are interested in developing.
There is also the '
Dev Tools Guide' sub-forum that you can refer to for any prospective developers who want access to certain resources and/or tutorials on how to work with certain programs and art styles.

Hope this helps, and enjoy your time here on the Forums! Once you get into the swing of things, let me know how your art progresses, would love to see its progress over time and provide further pointers for what it is worth
P.S. You've got lovely taste in games..... btw that's for sure
The pixel art in Aurelia and how vibrant the art form is quite a treat for the eyes......
