Although it is not as straight forward als regular climbing, once you now the basics it is not that difficult anymore. The most difficult part is making sure you aren't in any dangerous location. If the sun gets out, there is more falling ice, if there is a lot of snow, avalances can occur, climbers above you can (and will) drop ice on you or even drop ice-screws, carabiners, etc. During the whole day you are looking at the risks and making sure you are safe.

I'll try to make a next post later today!
