Thanks very much. Im a total beginner yet and i just made the registration so i posted few things that arent horrible, so i got nothing good yet. You feedback is very appreciated. 

The red pixels are a nice addition, second lightsources are a great plus!
However, these red pixels placement seems a bit erratic. You already have a brown colour in the palette but you're not using it much when it could really help smoothing the transitions between different colour zones.
