Not my 'bag', but very well done. The Krote looks like it might have started life as a M60 turret, or similar. Nicely painted and weathered. Not in to Star Wars, so don't know if that craft is good or bad. The last one looks like a pre-built toy I'm afraid.
I wouldn't know a 'X' wing from a chicken wing at McDonalds ! (Mind you, I wouldn't know a burger from a chicken wing at McD's !!!)
Jan, what garage ?!!
The Battlestar Galactica model was an AMT model from the late 1970s. About 1/48th scale give or take. And the X-wings might actually be toys that are repainted and modified. I had the former Galactica model and my brother... god rest his soul ...had the latter.
