Ye, pentagon looks a little to much blurred :/ Mouth needs to be raised and there are to many plates in the back in my opinion, looks like a overkill. Runes are a little bit to hard to see, should make them more visible, the nose seems a little bit weird and the eyes are too wide imo.
+ Small seam :V
If we look away from the faults, I like it...Better than I could have done.
