Updated version of my Hammer Tank concept for reference by Deviant Resident and 3D-modeller VMetallic's Hammer Tank Render;
The updates are mainly slight shape adjustments to remove rough edges interpreted from my original image (located in my deviations section under "game development art"), and to get it more contemporary-looking.
Inclusion of reactive plate armour (the slightly paler panels on the turret and the skirt).
Inclusion of Elite-level rooftop gunner (granted automatically when the tank reaches the top promotional rank). This form assumes either version of a fixed front-facing gun or a gun able to turn independently of the turret (the side flaps of the hatch turns with the gun in this case);
*Note that before then, this hatch is closed and there is no gun attached.
Sloping front-face more dominant part of turret, taking up roughly half its length
- Turret's front and sides now get an extra layer of armor,
- small red tiles/boxes help add more team-identification
- crew hatches and optics slightly re-arranged. Now both hatches are on the rear and both optics are at front-ish (although the commander's periscope is actually still much higher and further back than the gunner's sights).
2- The height of the 'cockpit' section is now reduced;
-the red boxes on the sides are now shorter also
-The fuel tank is now in the middle and lower
-Exhaust most likely lower as well. (or alternatively, directly above the fuel tanks)
3- the front slopes forward more, giving the tank's slope a lower angle.
4- The driver's visor is now smaller and part of a crew hatch
5- Gun is longer (by extending the segment that comes directly out of the mantlet (labelled segment 1)
6- corner cut out of front of the skirt.
7- potential widening of chasis (from left/right sides).
Overall VMetalic's model remains intact, with only some proportion alterations, and additional details to stick over top.
PS- VMetalic- you may want to wait for the upcoming Mauler Alternative before adding these adjustments;
Although it too largely utilizes the same proportions as your model, some of these adjustments may not apply to it.
