Phew. That background took about 18 hours of work to trace. But here it is: Twilight's underground laboratory from Feeling Pinkie Keen. For all your scientific needs.
IMPORTANT! This background is supposed to look like this: sta.sh/0dpq1q34xt4 As you can see, there is some stuff in front of everything that is supposed to cover characters etc. If you want to achieve the same result but don't know how to work with vectors, then try putting this in a separate layer: sta.sh/0157ofglm2a0(Not useful for MS Paint fans, sorry. )
No, when you make a vector by tracing (i.e. directly drawing over) something you found online, then it's just a resource. It's only art when you make a vector without tracing it from something someone else made.
