Update

Here are the pre final designs for both of my alien races. I have done two designs made up of my favourite parts of the development designs. From here I will combine the best parts into a completed and final design. I have been getting feedback from peers to see which parts of my designs are the best. I have had mixed reactions but generally my feelings are the same.

Personally, from the savage race I like the design on the left most of all but i am partial to the face of the design on the right, I may mix and match for the final design.
For the passive race my feelings are the opposite, I like the general design of the design on the right but prefer the head on the left design.
