UV problems

Unfortunately, I have hit quite a major problem with my model. I mirrored the alien and began preparations to create a UV map. However, when it came to unfolding the UV map out, it simply would refuse to work. I believe this is due to a poor topology, if I had begun with this in mind I believe I would not have a problem. Unfortunately, as I cannot pin down what the exact problem, I have to now use the pre-made model for future workshops. I will have to make sure to research a lot more into proper topologies so this issue doesn't repeat itself for the cinematic we are creating.

With the new model, UV mapping became a lot easier. First I made a planar map of the entire model from the front. I then cut the UV edges of the limbs and separated them out. Finally I unfolded the UV's out so I could then paint them with a texture.
