Firstly, a question: are you connected to the subject in some way, in business, or whatever? If not, skip this part. If so, then you have a conflict of interest, and thus it is very difficult to write a neutral, acceptable article. If this is the case, then we strongly recommend that you do not create the article. There are options available to create an appropriately sourced article in your user area, and then request that it is created. Please read this essay on best practice, and the business FAQ
Next - notability. In order to have an article on Wikipedia, the subject must meet the notability guidelines. The simplest, most important one is the general notability guideline, which says a subject needs significant coverage in reliable sources that are independent of the subject. That carefully-worded phrase explains quite a lot;
Significant coverage - such as, a number of news articles about the article topic - not passing mentions
Reliable sources - well, this is defined in some detail in WP:RS, but the essence of it is - something that is generally trusted - such as the BBC, CNN, The New York Times. Books are good, too. Blog-sites are rarely reliable.
Independent - we don't use primary sources, such as the persons own website, or their publishers/labels website, or anything like that. We avoid press-releases. We want secondary coverage - other people independently writing about the subject.
In the case of this article, looking on the internet, I am unable to find any appropriate sources, and therefore I think it will be difficult to establish notability. I'm sorry. I do understand your point, that the person has produced all this widely-used artwork, but unfortunately proof that the art exists is not enough. We would need to see coverage of the artist - articles about them, not about some album-cover that they made.
There is another important point to note here though, and that is, you can work on articles in your own user space. I have just copied the article to user:Tativ79/Adriana Rebold. That can stay there forever; it is not in the live area. You can edit it, improve it, ask for help with it, etc. If, eventually, you are able to add suitable references (as I have described), then it could be copied back to the 'live' area.
I suggest that you consider working on some other existing articles - perhaps something of interest.
I hope that you will continue to work on WIkipedia, and I assure you that I will help in any way I can. For more help, you can either;
