Lucca,
Holy smokes! I did not expect such a confident write up from someone so young. (You look young to me -- I guarantee I'm a bit older than you.)
Anyway, confidence is perhaps the number one thing you need when you are starting out. And your sense of confidence and your focus and sense of purpose all blew me away. Right from the opening -- that's a great opening you have there.
But first I looked at your portfolio and thought "I hope this guy mentions his range of styles" and, sure enough, you did exactly that. So that's terrific.
Here's what you might do: You might write a sentence or two about your professional experiences. Just say someting like, "I have sold illustrations to _____, _____, and _____."
That tells people that other people took a risk on you and they seem to have been pleased with the results.
Also, if you do have another style or two to show us, do that. I really noticed only two styles ...
If not, you should probably post one or two more illustrations whether they are in the same style or not. And, you don't have to post only items you've sold, so feel free to sit down and work out a new style or two and whip up some new samples -- as long as they meet your standards, which seem pretty high.
Another thing to say is "My illustration are appropriate for storybooks, album covers, CD covers, posters, marketing material, graphic novels ...." and anything else you can think of. Sometimes a customer is looking for a book jacket cover and will pass you buy simply because they didn't see the words "book jacket cover" in your write up. I'm not very technical, but apparently people can do a "keyword" search to find workers and if you don't litter your write up with the right keywords you could be passing up opportunities.
You will do great over time ... expand your mind from a business point of view. Create a business that reflects your ambitions ...
Good luck. I'm impressed.
