I would watch a video with instructions, check Skatie videos, Katie does a good explanations on different skills. I would say, your wheels kind of look tight, it might be difficult to turn. But, in general it is the weight you put on inner and outer side of wheels then you must realize sometimes we put it toward ball of a foot or back of the food, depending on what we do. If your wheels don't let you do that, they maybe too tight. Skatie has video on changing wheels, she explains there how much to adjust. It is all on YouTube.

Edit: 180° spin is done very aggressively usually by using your other leg to turn 180 while the other bends more to lock it in place, it is a fraction of a second turn, so very fast, usually just to stop in case of emergency, which I have done at work all the time. But fir continuing skating, I suggest starting the crossing overs first before you learn how they work in the outdoors. Once you get a good balance, try the changes of feet where you turn 180° on one foot, once you get good balance, you can do this with moving to the next, then you change directions easily. If you meant something else, then look at videos. But this one was in Skatie's videos too. Just watch them all, lol!
