I agree completely with Romain. The figures are finished with top quality painting and the m/c is also superb. The scene needs work as it isn't set up very well. At the very least a better base would show off your brilliant painting skills on the figures and bike.
Perhaps a narrow country road,two guys stop to examine a piece of discarded German equipment? Maybe question a civilian? Even just look at a roadsign,something as simple as that.

Thanks everyone for very informative and valuable comments, especially Mr. J and Romain. You all propably noticed that I even did not name it correctly since this is my first work in such category. From now I know that it is just vignette or just a little scene . I will try to improve my little work gradually with your help.

About blending the Acrylic color, I just found the information on the internet says that it is better to achieve this by using color retarder. Anyone ever try such way before? Please advise!
