I love the brushwork on your designs, but the form of the Rukoi doesn't seem quite on par with the Lapi. Why is his overbite so exaggerated? His feet look like they belong on a slow herbivore, but his legs work for a fast carnivore. The tail is far too short for the sting to do much in that position.
1. he need his jaws just for grabbing, rest does acid, so i think appropriate situation of maxilla and mandibula is not so important.
2. legs? huh, i think you're right, but i dont have much time so i wont probobly fix them
3. ill just remove sting
and i think you should cut a little Lapi and Widlisa, they are like one creature at the moment)
