By the way, it’s not allowed to name your item “professional” so I assume this might get soft rejected.
this must contain an eps file and would suggest an ai file too. if the design is made with the pen tool in PS it should be ok in illustrator but still needs some work to be perfected into correct outlines, layers, etc..
it’s a nice idea but the execution isn’t that good. The cat just looks weird and I don’t really see how it’s related to a 404 error page.
Okay, this is a vector. I suggest to upload this to the Vectors category. Remove all the nonsense preview and just put the vector on a white flat background, no need for any further text and bla bla bla. Make sure you save it as EPS version 10. Also check for open paths and unnecessary points.
Can you upload a preview image? Would be easier to say if it was rejected due to quality, etc..
