Okay first off I wanna say that this really made me laugh. I have seen many spoofs with the nyan cat but I have not seen anything quiet like this before. It most certainly is very original.
The technique used here is fantastic! It is just like Vincent Van Gogh's painting Starry Night. For those of you that have not seen this painting you can go to this >[link] It is a truly amazing painting. I my favorite part about it is that you can really see the brush strokes. Most paintings do not allow their viewers to see the brush strokes but I am glad that this artist stayed true to that style and kept the brush strokes visible.
I also love the vibrant colors the artist used here. It stays true to the original nyan cat video > [link] which is also amazing. This painting is a abstract modern take on it and I applaud it.
