Nice work, Delbert. A decent-looking model with nothing to criticize, really. Nice splattering on the rear. The paint scheme is really sharp, too.
If you want some suggestions for improving, I would suggest giving parts like the edges of the turret and hull a light drybrushing in metallic gray It will impart a nice, "heavy" appearance to the model Follow up with some very light highlights in silver---LESS IS MORE, but it will impart the look of a metal beast. You should try to do that to the tracks' guide horns too--they get rubbed down to the bare metal in real life.
I would have given the model an overall drtbrushing of light tan to simulate a pleasing dustiness and bring out highlights.
You could add some fuel stains around the filler caps. Some pin washes would help define your seams and creases.
For more of an advanced technique, I would recommend highlighting the base coat by spraying a lighter shade in the interior of the panels--"post shading" In reverse, basically.
Hope this gives you ideas for the next one!
