I'm sorry, but I don't think I can fix the eyes. First of all, they are made in the same cartoonish style as the gyrocopter's eyes, and I like the way they look even though they look unrealistic. But what really prevents me from fixing it is that L0w_Kwaliti's texture has eyes on the place where I placed the pupils. I don't know if l0w_kwaliti would like to change his texture, but perhaps I might ask him.
Either way, I'm quite fond of the way they look right now. It's not meant to look realistic, but rather cartoonish and warcraftish.
