i'ts a bit late today, but tomorrow i'll go for something transparent or white and reupload the pics!
looks good, but is the red background really necessary?
same goes for a few other images. jarring single color backgrounds are generally discouraged here as they're a bit distracting. Unless the images is meant to be seen on that particular color or shade, then i'd recommend making the bg transparent.
cool. i'd stay away from white though, that's even worse!
