If I understand properly circles which can be seen are artifacts. Am I right ?

not sure what you mean by circle artifacts, looks ok to me - there are some small dark circular areas but they aren't flat blobs - they are dense with filaments and I'm using DE - the circles around the central minibrot are formed from dense and less dense regions
