I have never used Lick paints, but I had a customer that recently did some DIY using Lick emulsion, and the walls were very patchy.
I cannot say if that was down to the paint or poor technique on his behalf.
--------edit-------- nah, your decorator is even worse than your plasterers.
Those photos are shocking.
The first two images are down to poor application of the paint. The last one is a failure to fill the gouges left by the plasterers.
The build of paint is not acceptable. I have seen better work done by first time DIYers.
Sorry, I don't know what to say. You were mugged off.
Your decorator has taken bad plastering and managed to make it look worse.
And don't get me started on the roller build up...
