Is this writing correct?

I don't think that studying science is more important for students than studying art.
I have two reasons why I think this way.
First, by studying art, they can improve their skill for drawing and their expression. Also, if they study art while they are young, they can
develop their intellect of art world.
Second, it is easy to get the picture they drew looked at many people by uploading on the Internet. Anime and Manga are becoming very popular, so they may be able to get people's attention by drawing such pictures
as Anime and Manga.

It was easy to understand you, but you still have a lot of work to do on your grammar, and on achieving a natural style. But you are already most of the way there – well done, and don’t give up.
