Hello. I am a pixel artist. You may use my sprites for whatever you please, as long as you do not claim that you made them.
I use GraphicsGale for the creation of all of my work. You will rarely- if ever see me create regular digital art, as I am quite awful at it. I will always respond to PMs.
I am always pleased to hear that you like my art, so feel free to leave comments, as they are greatly appreciated.
