Advice? Keep improving. If you really want to create games and/or art, just keep doing it. It takes time and effort to develop skills. I would just recommend taking notes from other similar projects and apply them yourself. Games can be hard enough to make on their own, at least the internet is around for you to gain knowledge on it.
I honestly don't know what else advice I can give. If you have the interest and passion for it, then sure, go for it. Plan what you want to make, and move accordingly, whilst also trying not get burnt out. 🤷♂️
