You can see in that first screenshot that your specular maps are not correct. A minor detail, but possibly worth redressing.
Well I can see from the first of your 'helmet' screenshots, that you haven't even done a new specular map. You can see the specular highlight from the old kit (there is a circle and an angled stripe going across the front).
Shoaib Akhtar face is looking nice.
I think colour matching needs some work. Rest is fine.
