Euwww, that guttering has seriously deformed at one end over the drivers side window. The engine room roof looks from what I can see above as passable, the cab roof needs some work but as you say, the windscreen is the biggest area that can be improved.
If it were I, I'd sand those windscreen edges smooth, then whip up a etched front screen and fix that one and blend it in, after cutting the resin back so that it did not show through the new etch and leave enough space inside for affixing glazing. Now I appreciate that might not be your chosen path, but for me that'd be the way I'd proceed.
The windows vary a bit (charmingly handcrafted I'd call it) but what I think would really improve the look of that body is filling and re-profiling the "corners" to lose that "drop" in the side elevation and to render the distance between windscreen frames and roof profile a bit more parallelish , or at least not reducing to such a "pointy shape" in the corners
There's something a bit weird going on with the windows in the drivers doors too.
Worth persevering with I'd have thought, concentrate on getting the basic shapes and proportions right then worry about correcting details etc.
Keep going

Who must get back to some modelling...
All the discussion about the nose & windscreens does highlight just how critical those areas are to the 'look' of diesels locomotives. It was those areas I struggled with on my brass 22, & never really got anywhere close in the end. I thought the resin body might've had the edge over the brass kit in that regard, but perhaps not..?
...Interestingly he photographed the same loco being towed towards Bath Road (Swindon?) at Pyle Hill on Dec 31st with accident damage to the "longitudinally opposite" corner, covered by a tarpaulin, trailing D831 and being hauled by an unidentified Warship...
