Um, not sure if there is a way i can say things without sounding harsh, but i'm just gonna go ahead and be honest with you. ^^;

first off, that image of kenshin is of unacceptable quality. maybe you tried to get it to fit your bg, but the not-so-smooth coloring, rough outlines, and the dirtiness don't really work. if you did, best to undo that. there is a difference between what you have and the actual painted look. if you did not deliberately make the scan look this way, then well, that image isn't usable in that state. (read: you'll either have to find a higher quality image or vector this.)

the extraction of the image is also poorly done. not only are there straight edges on the curved hair but also a lot of white leftovers. i also noticed that there is an evident cut-off in his hair -- not something you want to be seen. best to draw in what's missing.

the text also appears to be one brush repeated over and over again. the repetition is not necessary and it is not visually appealing. and when it comes to the main image of the bg, the cherry blossoms and branches, all i can say is that it looks like one heavily filtered image. :/ AP asks for a lot of original effort and creativity and the filtering doesn't communicate enough of that. it also makes the bg look low quality because of the spottiness it gives.

the overall image quality is pretty much the biggest issue with this piece. so take this one back to the drawing board and put some more thought and effort into it to make it better. work hard and ganbatte. xD
