I don't have anything to add to the wisdom other people have shared, but just on a quick critique note- I love your art and style and think you are definitely good enough to get work- I just question whether you have enough variety displayed on your website when you first land on it.
Yes, you can click on each image to see expanded examples and more variety, but I wonder how many people actually click on them? It would be my instinct to get more variety of characters and settings right when you land on your website. Clicking on each image would just be a bonus from there. I feel like whenever I see pro illustrators organize their website like yours, they also have a good variety on their landing page. I sometimes hear the advice from Will Terry that if an art director doesn't see evidence that you can do something, they will err on the side of caution and not choose you. Right now you mainly have young women characters in landscapes with some animal interactions and bugs. Old people? Babies/toddlers? Men? Interiors? Architecture? I'd consider if there might be a different way to arrange your work so we can see the variety right away. Pulling some pieces hidden away in your different sections would help instantly and then you could fill in any gaps with new pieces from there. Just something to consider! It can be tricky to figure out the way you want to organize your website for max impact and organization.
I also noticed that sometimes when I go to your website I get certain examples of your work, and other times I get three more examples on your main landing page, two of which doesn't seem to match with the rest of your style. (The girl with the net/boy with the star and Le Jardin Zoologique)
I also just want to point out that if you mainly like illustrating girls in naturey scenes, I think that would lend really well to social media and having your own print shop. I think the ones in your editorial section would work especially well. That maybe another way to diversify your income.
