Alien creatures

Since I have a few alien species I made up, I decided to draw some of them.
The species on the top, named Himples for now, is a small critter. Lots of people like to use them for living scarves and house pets. (They tend to enjoy sleeping curled around someone's neck and are pretty docile.) They have three toes.
The green guy is Tazad, who is a Scall. He is the only actual character drawn here.
The tan and gray canine thing is an as of yet unnamed species that are the size of large dogs. They're used for tracking, much like dogs. I'm not sure if they have five or six toes since I didn't draw the whole foot.
The bird thing is a species used for riding. Only people with money own them because they're carnivores and eat a lot so owning one is expensive. They are very intelligent mounts and can travel a long ways without tiring. In the wild, they're an apex predator, often running in flocks and bringing down large prey.
The riders are just some random species I added, and I didn't do a very good job on them either.
The last species is a more common mount. They're a kind of antelope. They were originally based of unicorns but the appearance has changed a bit and they all have two horns. The males' horns twist together while the females' horns grow straight. I'm guessing that most people get their horns taken off so it's safer to ride them. They're a very fast mount but some, especially stallions, can be hard to train and control.
I sketched this with a pencil before inking it. I did the color on the computer.
These species are mine so please do not draw them and claim them as yours. (But if you want to do fan art, that's okay as long as you give me credit.)
