I really like these, at first glance they are a bit plain bit
but that's exactly what battletech minis are supposed to be. Just like real world military machines they use a lot of drab boring colors. The downside is those colors don't help it pop while on the table.
With a close look to see the details I think you did a great job with the two tone tan which helps break up the diferant sections. I also really like the blue canopy lenses, so many people do the red jewel effects that it just gets old and the blue really helps contrast the tan color much better than the previous orange. The orange was well done but seemed kinda flat due to being close in color to the tan.
I do think that some more unit marking or numbers might be warranted, maybe some white identifier numbers or more caution markers.
The military aricraft I've been around are all usually monotone drab color but they still have lots of hazard markings around intakes and along wing steps etc. I've also seen a lot of that that same detail in place on marine and army tanks. The bulk of the vehicle is usually in olive drab, desert tan, or light gray and will have tons of white or black crew markings.
I think it'd be a very acurate way of addinga touch more detail onto the models while still keeping it inline with the fiction requirements. I know there's already few of those on the models already but adding more would probably be good?
If you want a super anal attention to detail the wolverine has two machine guns in the nose slots that aren't cast on either the plastic or metal versions, if you use a super thin wire you can add those. I used to try and add those but they always popped off if you even looked at the model, that was also way before I had a pin vise drill.
