The colours for the dark legs you've got are fine, my complaints were about your placement of the highlights.
You could make them solid-coloured, but I think it would be a good learning experience to work out the highlights. Where's your light source? The parts of the leg that face the light source most directly would get highlights, and all the other parts would not. Try to avoid highlights that are just lines, as those look like wrinkles or ridges, which doesn't fit the intended round forms of the legs; try to work with blobby shapes instead.
Is Akali the one with the spray can? I think the details you've drawn already are fine. You can't fit everything, so it's better to simplify and only depict the most important stuff. I also think you've done a fine job on the glow. There's not room for an explicit glowing effect, and besides, by being such light colours against dark colours, they already glow a little just due to the fact that monitors work by glowing :]
