They look good from what I can see in the pic. In the future I would do as mentioned above and put in either a clear cup, bag, or sterilite bin so you can monitor root growth versus top growth just to have a better idea whats going on below the surface. I would not remove top growth and make sure they are getting some light to be able to make the food they need to push out more roots. Also, in the 2nd pic cutting closest to the front, it appears you did not remove the wood to about a quarter inch above the highest node. This is something most do. I don't think it's a huge issue but it does serve a function. Also a clear bag on top for the humidity dome next time would also help you to view what's going on easier w/o removing the bag much & let a little more light through as well. Other than that I think you are doing a good job.. Be very light on watering, as that is the death of many cuttings! Good luck and keep us posted on your progress :)
Ps How many nodes are below the dirt? Hopefully there are 2 or 3, burying cuttings a little deeper helps to assure they can make enough roots to support themselves and not dry out too quickly.
