5 month dreadlocks

Is it typical to have dreads this well done at 5 and half months?

I'm going on 3 and a half months right now but i want to know if they should get like this. Below is a picture attached of my hair.

Thanks!

yours is a bit shorter and thats why its takin a bit longer but your progressing perfectly normally

2 months will give u that all important extra inch and really jump start em alot more
