Superb!
Tanker3 is right about the tracks on the old Tamiya kit, but I wouldn't worry too much about 'em. They look good as is!
As an aside, Tamiya didn't make a mistake, they consciously chose to mold the tracks like that for improved flexibility. If they had molded them correctly (with the end connectors in between each track shoe), the tracks would have been too stiff (like the infamously stiff Testors/Italeri M4A1 tracks) with the vinyl used in those days. With today's modern flexible plastics, Tamiya's newer kits feature accurately molded tracks.
