Im not sure about what you want suggestions upon. Please specify. Personally I would make some of the ornamentation on the "Spangenhelmed" inspired helmet with perhaps brass. If the helmet itself is in dark steel the ornaments could very well be in silver.
The garment of the breast have always been interpetated as leather as me although Ive seen it painted as metal several times. Elkhide was very popular to cover shields as well for body armour. Elkhide has always been in rich supply an were used commonly in scandinavian armies up til the 30 years war.

The PM viking was one of the best viking figures when it was new. Even still good its not the best on the market.
The best way is to imagen what kind of viking is this and what is his background. Newbie-veteran. Simple weapons, new shield versus wellused shield and weapons with engravings.
Rich-poor. If the later simple clothing coloured in earth colours and if rich he should have astoninshing fabrics perhaps of oriental production.
And so on. This to determine what kind of clothing and fabric he would be wearing. Simple, extra vaganza or in between.
A Hird(levy)man could be carrying a ring as a token from his chief as this was a popular give away to good and loyal warriors.
Very little foundings has been made considering shield and theres nothing suggestioning that they were painted. Not in finds or in paintings and drawings from that time. Perhaps only simple patterns or fields.
Raven has been used on standards at several occasions. This as ravens have a very dominating role in war. Firstly as a battle field scavenger and secondly Oden the lord of the gods has two ravens as servants, namely Hugin and Munin which translates to "Thought" and "Action".
Heres a pic of a raven from genuine viking art:
More of that:
Perhaps this could be used as inspiration:
More inspiration for shields can be found at the Foundre website, but caution, one must be very selective:

And Johan, at the next "Blot" Ill tell Oden youve said "Hello".
