Well, the sun kinda washes out your colors a bit---might want to try color-correcting them in a photo program next time?--but the model looks really nicely done. Really nice figure, too.
The mud itself is excellently done as well, although if I had to nitpick, it's a bit "red clay" for Europe--but I realize that that may be the effect of the sun's lighting?
Well done, overall. :)
