Thanks for the input, I made some of the changes you suggested. First, I moved it to the lower left, then I think I got the right font. Its Arial size 14 and 10, but I feel like photoshop might be screwing with it somehow.
I messed with the tracks and wheels a bit, it just hard because I obscured them so much with the skirt. I added in a new set of wheels and tweaked the skirt a bit, but some of the references I used don't really show the tracks as bending that way, though I might elongate and slope the rear area of the tracks to make it look nicer. At least I was able to change it a bit. I lost the green lines because they didn't read as anything and added a lot more rivets, made a lot easier by figuring out photoshop brushes so I can space and paint them super-quick. I also added a bit of shading to the turrets and skirt areas.
EDIT: Did a bit of touching up on it to show shading so you get the gist of it. Try to rework the roadwheels to they're a bit more circular, along with the tracks too as Eswube stated earlier. In addition, a 100mm gun in FD scale (IIRC...) is 5 pixels thick, and a 37mm should be 3 pixels thick. The 37mm should also be a bit shorter I believe. Anyways, it is a good start so far.
P.S: Fixed the font for you
