Hey, i saw your email but as i do this as hobby i seek only for free help not paid sorry.
Dear Kira - Read your initial post - maybe change it if possible to tell others that you are not looking to pay a designer for their work at all.
"So yeah im looking for pixel artists, I know most of you want only paid job even if my project is a F2P so for you guys : Show me what you can do and let discuss about the price -> shadownt@live.com".
Otherwise, the above quote reads like they have a chance to get paid for their work.
