Hi Shao Feng-Li,
Glad to see your following conscience.
I went though the same thing (well kind of...) a while back.
Here's the thread I started a while back about it:

After I left DeviantART I went to
http://www.Flickr.com.
It's a cool site, you can post pics at any size ( Unlike the
http://www.theotaku.com below). It's good to join clubs and stuff like that.
Also like anywhere else, it's important to use tags there too.
I also went to
http://www.theotaku.com where in their rules it says "Visual fan works cannot be pornographic or depict any sort of detailed nudity (e.g. exposed breasts). Written fan words cannot delineate any erotic content."
Though lately some people are really pushing it.
All and all these sites are pretty safe, but check them out for yourself and see what you think.
BTW Here are my galleries for example:

Also on another note, I made a Christian Anime Artist Group over a Flickr.com
Feel free to join.

Hope that helps. : )
God Bless.
