It looks good!
As of tips to improve, you may try cleaning some of the wash you are using in the open and raised areas. It seems to me you are applying the wash all over the miniature and that is OK as the minis are not that big and it is faster, but you will get cleaner shadows if, after applying the wash you clean some of it, you may guide it to create shadows and degradation too.
And you may try painting some red, white or yellow (maybe other colors, but just one or two other color at a time) in some of the details to make them more lively (even if it is not really how military hardware is painted in the real world). For example, you used red for the shoulder and rockets, use the same red in some of the other side to make it more balanced, like in the right leg (the knee or foot maybe) and some details in white, green or yellow as those are vivid colors that go well with red, maybe in the right arm.
The concept with beams is that hitting on target is not hard at long range but maintaining focus on a single spot to vapourise armor and hit structure underneath is much harder the further away a target is. Beams are also supposed to have accuracy at short range due to the ability to sweep a beam over a target.
The advantage of a Mass Driver/Railgun etc is a single impact that does huge damage at one location.
