Any comments/feedback welcome utilising new weathering skills as yet not perfected but am i on the right track.

Very nice work.

I am a big challenger fan and I used to intern for BAe systems and I got to see a Challenger 2 up close in person.

There are a few things I'd point out:
The CIP panels would have an even wear on the, More like a dusting where the white looks an even tan. Same goes for the white decals.
You are missing the mounting brackets on the front turret CIP panels
I love the tarp wrapped around the tank.
If you can blend the dust tarp wear a little more it would add a little more to the model.
Lastly, chipping was seen more so on the turret on areas of higher traffic, i.e. crew walking up and down the turret.

These are minor things but you have built yourself a very mine model. I've got so many other things going I can't even get to mine

PM me if you need some photos. I have a crap ton

Sean thanks, Im very much a beginner but had fun with this,tried a lot of teqniques seen on this site, practice makes perfect, in retrospect I probably wont weather as much on modern stuff and am still looking for a perfect result. I am a little embarressed by the pics but if you dont share you dont learn.
