An issue with some of the logos is the lack of contrast between the bg and the character. This is specially noticeable for Yukari Lin & Onn, Iroha V4 and, in minor degree, v-flower

Another detail,  I don't know which software are you using, but it seems the rendering method for resizing looks blurry. Generally in Photoshop I use the bicubic sharper method when I have to resize to a smaller size.
