wohoo a really nice job in extracting that image
(did you use the clone stamp for the hat part or just vectored it? O.o)
and this is where the length of the sig betrays you
being rather empty its just too dam long imo ~ so probably it would look better if you chopped of some of the edges :3
i really like the colours however that is one problem...whilst the background is that of the day and quite bright ~ youve kept the colours on matsuri from when you extracted it...having a dark purple hue contrasting onto a clear light blue BG doesnt fit imo...so i think it would look better if you did some colour changing :3
other than that it looks really nice ^_^ *thumbs up*
