Animating - delayed. Working on Texturing instead

Found some problems when I tried to animate our main character (Sophie)- so Asa sent the model back to get it re-done and checked. While we all are still waiting for it, I was told to re-do the train model. I realised how simple-minded I can be since the train texture I did earlier is too simple - looks too plain.

I'm still learning how to texture so I'm trying my best to get it right - Below are images of my attempt to re-texture the train and I hope it's much better. I used the bump-map technique under the colour i.e. Gold with another image:


I'm starting to get use to using the UV mapping techniques - below are screenshots of how I used different UV mapping; here I used 'Automatic Mapping', quite useful but not always works correctly. See the textures go very messy so I had to highlight the areas and then select 'Automatic Mapping' again:

AFTER

Like I said before the 'Automatic Mapping' is not always realitable - for the roof of the train I use 'Cylindrical Mapping' as the roof is curved:


And here's the finalised texture of the Train:




Not too sure if this is better so I'm just going to have to wait for everyone's responses - I will double check the textures of the train before I send it to Asa.
