I wanted to start makeing walls, so I did this pice just as welcom to walls, please tell me how I did and general tips and hints for makeing wall papers.

The text of the quote is way too boring, it has no bite and it's too corny, the pictures seems a bit low quality to me as well but nice concept overall

The extraction on the cards looks decent. The area that could use improvement is the background:
1. Solid black never makes for a good background unless there is a specific style you are mimicking.
2. The extraction on the FSN logo needs to be cleaned up so that it doesn't look so aliased. The bottom left looks like there was some white text or something that you need to paint in red to match the logo.
3. The text font is too "boring" for as large as it is. Spend some time at dafonts.com and find a more interesting font for your text.
4. The symbol in the back is also too aliased and needs a better extraction like the logo. Being simple lines, you may even want to vector it.

For submission to AP you would also need to place your signature at the bottom of the wall. Good luck and I look forward to your next version.
