Nice work-- and welcome to the forums here. 
Being that you''re new here, I'd suggest that you should really take the time to post the photos here though. A lot of people here won't comment on a build if they open up a post and there's nothing but a link. Also, it helps if you take the time to share your methods, what you did, etc. It makes for good modeling banter!
One thing I will suggest is that you paint your Jagdtiger's barrel dark gray--almost a black color. The debate has been pretty much settled that although Germany used red primer on their vehicle hulls and accessory parts, gun barrels were primed in a dark gray. You can look this up on the internet if you doubt it---take a look at this link,.
