Sci-fi series sketch dump

Some random sketches from my sci-fi series, most of it is from the first story that I am doing but I did sketch out all the heads of the principle species so from top to bottom Av'Arul, Maika(White-Ash, also they tend to have very thick hair but I wanted to show the shape pf their heads), Mystik, and Verbae. Three of the other sketches are of Omni Koel the other woman is Robin and the man is Captain Ralo Toft and then the Av'Arul at the top is Ce'vill Kalum. Check out what I have done for the series so far mekari.deviantart.com/gallery/…
