Correct centurion.

[Tarbicus]

Here are two grave stele of actual centurions in the RA Image Database:

The first wears hamata, the second squamata, and both have pteruges (the strips coming from beneath the armour). Pteruges are often discussed and there are two main camps of opinion of what they are made: multiple layers of linen sewn or glued together to make strips, or leather. There are also suggestions of wool and felt. For more info see Travis Clark's comprehensive website:

You should also get your hands on Graham Sumner's [amazon]Roman Military Clothing 1[/amazon] for an examination and reconstruction of clothing for the period.
