Sorry if you not understad me im spanish jeje.
About the camp and grass is easy, for the color, detail, perspective, stile... and view in a second that the camp and the grass not is make for this.
About the camp i think need more details. The front of the camp for my is perfect (the enter) but the other part you can view perfect the pixels and not is more good...
I view your works, and view your style i s very good, detailed, sel-oul, anti-alias.... and much color, but the camp i think is an incomplete gfx.
I will try to put any of dithering for make shadows or make a trick for appears is a little transparent, make the camp alternate 2 colors, etc...
