Agree, picture 2 looks great and I like that it took more time to get the stove up to temp again. At 600 F stovetop that seems like a perfect burn. For the first picture, try not to shut down the air that much. If you needed to because the temp was already so high, start dampering it down a bit earlier but just by a bit. When closing down the air, watching the fire is more important than the stovetemp (which is important if you want to know when the stove has reached peak and settled in). I suspect with better seasoned wood you can close the air even more and get more heat out of your stove. I am sure you will enjoy the next winter.
If you want to maximize your wood load, put two or three pieces of short wood sideways (E-W) in the void left by the coals in the back of the firebox (wear welding gloves!). That gives you a level surface together with the pile of coals in the front, on which you can put the splits lengthwise (N-S).
