if you guys do not mind me using your art, please post your name here.

uh What?

What do you want to use it for?
What pieces you do wanna use?

There's a TON of unanswered questions, and this is a completely inappropriate way of getting permission to use someone else's art.

In any case, whatever your reasons may be, the answer will most likely be 'No you can't use my work.'

If you need artists to make game graphics or something, generally you need to either pay them for their work, or get volunteers to do it specifically for you.  You can't just take done pieces and use them for your personal needs.
