Human and Alien Characters [Tusserk]

Hi all, I am requesting one of the great and talented artists here create for me 3 characters: 1 Human of average hieght and build with dark brown hair, grey eyes, rugged appearance in his mid-30's wearing a slightly modified version of the ship uniform worn by the crew of the NX-01 Enterprise. The first alien species needs to have wolf/canine like legs, hands with 3 fingers, and a head/face similar to a Horned Lizard from the state of Wyoming. Their color if you create more than one can vary between light tan to dark brown. The 3rd alien race needs to stand roughly 6'4, covered in leathery skin with features similar to those of a Koala Bear. Though the nose can be smaller and the ears more pointed.
