Would it be possible to get a new signature?

I was hoping to use this picture for the signature: http://i2.photobucket.com/albums/y23..._by_Aile_M.jpg

I also found this avatar, if you wanted to do something similar to it, or if you had a recommendation: http://i2.photobucket.com/albums/y23..._by_RazAvs.png

Thanks!
