Hi Mulder. Welcome to the bearded brotherhood

You have some good growth there for 4 weeks. Do not be put off by other posts with fellas that have mountainous amounts of facial hair after 4 weeks. We aren't all built that way. My beard growth is very very very slow. Yet it grows long when left. I have friends that can grown a beard within weeks. Sadly, this is not me.
You have some very strong growth on the Chin and tache areas. Hopefully this will mean good growth under your jaw. Cheeks can be a pain in the backside and the last thing to catch up and grow in. 

My my advice keep at it buddy , it won't be easy, trust me I've wanted to throw in the towel at times as I've felt either self concious about my facial fluff of my moustache getting into my mouth. Patience is everything , it really is, you have to battle through the negative stages to achieve something to be proud of. Any Beardsman on here would say the same. 

Keep at it. Looking good so far 👍👍
