One question though. Did you take out white space or something or other because when I put that in comparison to any other sprite off of the internet (unmirrored of course), the pictures are unevern (that version will be in my sig until figured out). If you didn't, just tell me where you got the original sprite because maybe they did something. You did nothing wrong and I thank you, this is just an OCD type thing for me.
Maybe shrink the larger sprites and put them into their groups. The birds and lugia near the upper left, the beasts and Ho-oh in the upper right. The weather and Kami trios in the lower right, seperated but both groups down there. The Titan and Tao trios (the gen four and gen five dragon trios) in the lower left. Latis in the lower center, the dream duo in the top middle. THe Deoxy in the middle on the left side. The cute legendaries (Shaymin, Mew, Manaphy, Celebi, Jirachi, Meloetta and Victini) on the right sde. Mewtwo in the middle surrounded by the Musketeer quartet and the lake trio. The golems and Heatran just kind off spread about. And no Shaymin-S. Sorry if this is too much, but it is just a thought that you can edit to fit. And thanks for all the work.
