Hey man dont take this the wrong way but here are some pointers.
Berms- build your berm in gradient. Click "Gradient
RADIAL ADD. Set brush focus to "0" Start brushing from outside and work your way in the graient until the angle that you want is aquired. From there give a small smooth focus at "100" and strength at about "-25".
NOTE: If you arn't satisfied with the height (too short) click "U" and Brush over again and smooth. This will make it Twice the size.
Any questions let me know and shoot me a PM
