If you feel inspired to do a fanfiction, then you can step away from your original work. However, I don't recommend it if all you're seeking is more views/fans. It might seem like if you do it, you can gain a fanbase and then start to do original stories and your readers will follow you there too, that's actually in most cases an misconception.
Even if you're an artist and all your doing is fanart, you might get a lot more fans, however, when we switch to original artwork, they might not be interested in your work anymore. Because you got yourself put into a certain type of creator and your fanbase is generally just following for that reason.
It can take a long time to build an audience, because of the number of series on tapas. But, that shouldn't be the reason to stop working on your original work. You can step back and re-work it if you can improve it. But, don't stop because you don't have a big audience.
Personally, I rather have smaller audience that truly enjoys my original work, than a large audience who like me because of fanart/fanfiction.
