@albertov, not sure if I get the joke about a hidden chicken :)

I like this tileset, you did a good job! Barrels need a shadow too, and a hidden chicken. Also, a ninja fits in almost any environment, hehe...

Yes, I surely need more practice with characters. Just have a overwhelming passion for the environments - that's the case.

Great palette and tile placement . The military base/facility theme jumps right at you, well done! I also like how you did the metal and shadows. Everything looks very harmonic.

The characters and green barrels do not have the same quality as the rest though. That doesn't mean they are bad! Just not as carefully and passionately pixeled in my opinion.

Cool mockup nonetheless.
