Darimc- Not a bad start, the textures look a bit washed out. They are issing depth. What photo editing program do you use?
If you use photoshop I recommend the following tricks to help get a richer texture.
1. Use the magic wand tool and select the outside area of the UVmap, then go to select>inverse. create a new layer over the top of you original UVMap.
1a. Chose select>modify.expand and put in 2 - 8 pixels. this will ensure you do not have open edges.
2. Chose the Fill tool set the opacity to around 36% and chose your base color and fill the selected areas in.
3. Deselect the area.
4. in the new layer go to the layer options and select "satin" set it to "soft light" and then chose "pattern overlay" set it to "overlay" and set the scale to the desired texture strength, you can even hit the to layer button next to the pattern. then hit "ok"
This will give you that nice rich texture, you will have to add the shadows and highlights manually unless you use an Ambient Occlusion. Using AO for reference is not a bad idea but it is better to paint the shadows on in my opinion. you can repeat the same process by using the Marquee tool.
I hope this helped you.
