Well now, here's an oldie, but a goodie. You're right, it's perfect for practicing new techniques. Everyone will tell you it's not worth fixing up, but I did.
The Tamiya Panther G indy inks fit perfectly, even though they are not recommended by Tamiya. Ditch the rubber bands lol. They work, but you won't be happy with the results, I think, because I wasn't.
Keep it around for effects practice long enough and you'll either find it's ultimately not worth the effort, or spend a lot of time working on it, as I did, and make something awesome out of it.
Okay, now that the standard preamble is out of the way...
You did well with it so far. There is a lot of room for improvement, but don't stress it. Most of us have built this kit at one time or another. As I stated above I upgraded and scratch built some stuff, tried new ideas, and added a commander.
I'm mostly happy with mine, but I'm still kinda working on it once in a while. I lost interest and I've got the newer Panther Ausf G kit and it's a far better kit right out of the box.
So, yes. Hell, yes! Keep 'em coming!
