Very nice! You are a natural.
A couple of questions: First picture in the bail - is that a fine wire or a piece of hair? On the left top loop, is the tie-wire stand alone and what gauge were you using, 26?
A couple of suggestions: First picture, the top loops - for the (what I'm assuming) is the stand alone tie-wire, what you want and need to do is to wrap your tie wire 2 or 3 times around a single wire first. Push the tie wires together as good as you can with your fingernail and then do your two wraps around both wires and then around the first single wire another 2-3 times and push it all together tight again. Snip your tie wires as close to the bottom of wire as you can and pinch those ends tight against the wire with your pliers, but not so hard you mark the wire. What this does is "lock" that tie wire in place so it doesn't come loose.
The same thing with the stand alone tie wire on the back of the cab. Pick a wire (I would use the non-twisted one) to start on. This technique locks that little wrap in place and also makes it nice, neat and tight.
On the top right loop on the front of the cab - you did your 2 wraps around the twisted wire, came under the loop and then over the loop and back down to the twisted wire at an awkward angle. A better version would be once you came up under the loop, do 2 wraps around the loop before heading back to the twisted wire to continue on. It would then match the left hand loop and it would look neater.
The bottom back of the cab is a bit of a mess. There's a single weaving wire just dangling there. Not sure what that belongs to. When you're weaving, make sure you have enough weaving wire so you can finish without having to add a new wire in. Especially if you're using copper, it's not that big of a deal to cut off a little bit of copper as scrap.
What I would have done is when you get your weave to the first (semi) loop, wrap twice around the base of that loop and then bring the weaving wire to the next loop and single wrap up the base of that loop until you get to the base of the twisted wire. Here I would do a figure 8 weave (over one, under one, over one, under one) a few times to really tie them together. Then a few more single wraps around the twisted wire to lock it all in before you snip the wire at the bottom of the base wire and give it a squeeze with your pliers. The figure 8 is a good way to tie wires together without wrapping around two wires at once, which is less tight and not as neat.
Hope this helps a bit! You're doing a great job.
