Rating: 5 I think your painting skill will improve over time - more highlighting etc. But you must never again paint green under brown static grass like this. I mean never again. Paint the ground brown and you will be fine.
Rating: 5 Real constructive "apabror"??? Paint is too thick and the colors too busy, try less colors and stick with one set of colors to scheme against. The banner and runes are unique and original, but need some fine tuning, they do look a little sloppy as well.
Rating: 5 The paint looks a little "globby"- did you thin it down with water? a little trick for banners- make them on your computer with photoshop or something (three times bigger) then shrink them down and print them.
