Well I just thought I would keep poeple updated as to where I was with this. I haven't been able to post for a while cos I have been really rushed at work, but I have sorted that little problem out now.
Right now I am working on one of the hardest bits for me, the stern (the back). The problem I had was that is has a lot of nice detial and carving work. In the end I found a little solution. I projected the reference photo onto a plane and just cut around it. That way it is loy poly and quick to make, but it also gives the impression of having some depth rather than just being a flat texture. The bit I am working on right now is the crest on the top of the stern. I will give you guys a close up later.
As always, comments and critism are always welcome.
