Hello and welcome c:
Zerochan is a website with all kinds of high quality pictures. It's great when you're in an artblock and need some inspiration. That's usually what it does to me: give me inspiration :'D
Or you can browse there for anime characters you stalk or wallpapers.
I've been a member here for 2 years and I haven't learnt anything here...
So I can't give you any tips.
