These low poly cartoony models are made mostly for top down shooters or similar genre that doesn't require too close inspection of the models. But as said they can be used however you desire.
All textures are: 512x512
The wall model, barrel and sword all have respective specular and normal maps. I also included the raw .psd files if you require for some reason to change the textures in any way.
Additionally, for the sword there are a few more patterns in the .psd file if you would like to use that, keep in mind, those patterns do not have a normal map and you would need to create your own if you would use that pattern.
