Well, i uploaded the original concepts that i have left on my laptop, from back when i used to sprite for several 2d games.
I have been a spriter for several games, which include Graal Online (private servers), HVO (Hidden Villages Online, A naruto fan mmo) etc.
I focus mostly on writing these days though.
I have sprited and worked under the following names, though now im just Kitsunami.
And no, i dont claim originality on those names. Most likely if you see some fantastic spritework by one of those, it probably wasnt mine. All thats mine is upped into my image gallery now.
I dont claim to own star trek and the likes, nor its concepts. They are the properties of paramount and so forth.
The few star-trek themed images are fan-made concepts.
