After 2 days of weathering my rhino(I had to let the washes dry), I finally came up with this which looks good IMO. I actually made a mistake which became good weathering. I found an old brush somewhere in my room and decided to use it as a wash brush. Turns out that the brush was already used for oil paints. I thought I had to clean it up when I noticed that it actually looked like real dirt. Anyway, here it is. Enjoy!
