Did you put it in the wrong category, or did they?
Write a ticket to support and they will probably change it for you.
Does it count if I work for a big company and use my own items in the designs I make?
There’s not really anything that anyone can help you with. You just need to be patient. Nearly every item that I have took 7 or more days to review. I’m sure the marketplace gets hundreds of items to review every day, and everyone wants a fair and good review, so it takes time.
The review process takes a long time, it’s just something you have to be patient about. I often have to wait around a week or just over for an item to be reviewed, but just wait and you will eventually find out if it’s accepted or not.
You could also try LinkedIn. Though for something like that, you could always ask a friend or someone you know to do that. I used to work for a guy who owned his own successful web design business, it was just him and his friend who was handling sales, social media, promotion, marketing, etc.
You don’t know what a bar code is….?
You DON’T need one, but most tickets have one. It would just make it look more like a ticket.
A bar code is used by scanning it with a barcode scanner. This tells someone how much the item costs, whether the item is activated or not, etc.
A QR code is a visual link to something on the internet. If you scan this with a QR scanner (your smartphone) it would open the corresponding website. This is a good and fast way to directly link people to a website so that they can see information which wouldn’t fit onto the printed item.
I’ll nominate this Christmas itemhttp://graphicriver.net/item/christmas-styles/3320989?WT.ac=portfolio&WT.z_author=Xiox
I’m a little confused by your question… or statement. I’m not really sure what violence has to do with this, but if your item shows highly violent images it probably won’t be accepted. I’m also not sure what you mean but pasting Illustrator graphics into Photoshop being a problem, of course the graphic wont be vector anymore unless you do it properly, but that’s the only “problem” that I see with that, that shouldn’t affect whether it gets approved or not though.
