I am currently working on my race and although I am by no means an artist, I have made some sketches to show the appeance of the creatures. One of males (front, side and back view) and one of females (front, side and back view, too). I made close-up sketches of their eyes (both males and females), their tongues (they have split tongues), their teeth (really can't easily describe this one) and their ears (pointed, so yeah).
As I said, I am no artist, but you can tell what is what and all that.

Now, will I have to write desciptions of these things as well, or will the illustrations be enough? Same goes for other stuff I will be sketching later (aritfacts, ruins and such).
