I am applying for Artist, Texturer or Level Designer. I think I would be able to help significantly on all of them.
Your age :: 13 and soon to be 14
Previous works :: I haven't ever made anything popular enough for you to recognize but I have been playing minecraft every day for three years and I am very good with command blocks, details and terraforming.
Have skype? :: Yes, my skype is thesphinx140 but I would feel uncomfortable skyping with adults because I'm in my early teens.
Your inspiration to work on a game :: I really like the creative aspect of minecraft and the feeling of making a redstone contraption that you have never made before and seeing it work. (Example: I made a mind control machine using pressure plates to control a villager. It used the new @e selector in 1.8)
Why we should pick you :: I really don't have any proof of it, but I love building, I can play minecraft all the time when I'm not at school and I consider myself a good builder. I always keep up with the updates of minecraft (Example: I learned how to use command blocks several days after they were released.)
