Texture deforms on render

Hello, this is my first post here,
I was just making a character for a videogame, and decided to have fun with the textures, but here’s what happens…

watch the right eye, it stretches up when I render, I am not very experienced with texturing so I have no idea why this happens, smoothing does not have any effect on the stretching. Mapping coordinates are set to UV and Projection to flat.
Other than setting those things I think I haven’t done anything weird, so I hope anyone can help me.
thanks in advance. :smiley:
