Auto retopology bad results

 I'm trying to get a retopology done out of a model that has some close together holes in the head but I keep getting bad results. I've tried the stroke lines shown in the picture below and slight variations like putting an edge loop around the thins pieces of skin but every time I get I similar result to the one shown in the picture where at least one of the holes is completely covered and the back part of others have those spiked polygons. I've also tried cranking up the poly count for the auto retopology but had the same happen. I've also tried to add more guides but it seems that if I try to add more than the amount I have shown in the pictures the whole thing goes crazy and the topology becomes really bad all over the model. I've seen people get some really good results from complicated meshes like this but I haven't had an auto retopology that seemed good enough so far.

 

Is there something I'm doing wrong?

 

PS: I'm using version 4.5 BETA 15

As an experiment, in Surface mode, decimate 75% and with Autopo, bypass the two intermediate operations letting Autopo figure it out and then use auto-seams in Retopo to prepare for unwrap. You wont get a classy edge flow but it will be suitable for non-animated use. For animation, use manual retopology.

I tried what you said and I got a little better result but still couldn't get something that worked for the thin hole on the side. In the end, I just ended up using a decimated version of the mesh and it worked fine enough for the animation that I wanted to make.
