Because I am a masochist, I am making my first short animated film with these two characters. Why start with simple two legged humans when I can do a 6 legged massive Bison and a Lemur who flies. Momo and Appa folks. Wish me luck. (Yes I know they are not perfect, it's a process lol) 
Hey we all have to start somewhere!
I think you can do a little blurring on the texture to make it less pixelly and if you need more resolution I believe you can do a higher res image or a couple other things.
I don't have textures on these yet. I haven't gotten to that in my learning yet lol. Soon though.
