Hi Matt,
Firstly welcome. I'm a newbe too, and I have only just started building Allied Armour.
Your kit looks good to me, nice finish and some nice added extras.
It's a nice kit to build, like all the Tamiya stuff fits together pretty well.
Here's a picture of a rather sad work in progress for the same vehicle. So take heart, I think you've done a great job.
I don't know if it's PC to post my picture in your thread but please don't think I'm trying to steel you thunder or anything else. Just though it might interest you.
Keep us posted on the dio it sounds interesting, we don't see that many British Commonwealth ones so I'll look forward to that.
What's next after the Cromwell? Some Sherman's or Churchill's or perhaps the Comet????? I've been attempting to get some Sherman's built but every time I think they are finished I discover something else I should or shouldn't have done - LOL, LOL
Thanks for posting your pictures and good luck with your dio.
Cheers
Al
