Hey Edson
Welcome here!
...the good...
I love the color you used. Its not to dark.
The machinegun looks great!
Your ruststeaks are good.
Smokey barrel is good. Not to much, they also clean the barrel once and a while...
Wash is also nice.
...the bad...
Your tools look a bit to new... Your right with the woodcolor. I use a sephia wash to finnish the woodlook. The metal of your tools are to silver. I use black brown mixed with a small bit of grey green (i use vallejo colors) to make a "weatherd" look.
Your tracks look a bit to grey. I think you drybrushed the tracks a bit to much silver...less is more in this case (even if the tank was driving on a cobble stone road).
This is how i make a towing cable. I paint the cable black brown. Then i paint the the ends of the cable in the color of the tank. To make the tear and wear, i cut a small piece of sponge and dip it in the black brown color. Sponge the most of the paint on a piece of paper to the point its almost dry. Now you push it gently on the ends with the tankcolor and stop when it suits you...
...the verdict...
Well, its a bit hard to call it a verdict, every one has his "style".
Its good Edson, its good
Regards,
Remco
