Welcome to the board.

3 weeks is a short time in "beard years". You have potential for a nice low beard, but at the moment you don't really have the same amount of coverage as your goal pic. However, don't let that discourage you. Many here have posted goal pics...did they meet those goals and end up with their dream beards? Not all of them. But a good bit ended up with great, unique, and respectable beards that they would not have had if they had not given it time. 

May I ask how old you are? Many here, myself included, weren't able to grow much until way past their 20's, 30's, and even 40's. 

So, give it some time. Check out some threads for some inspiration. Be sure to read the Rules (its a sticky in this forum). And above all else, keep growing, and I'm sure you'll be pleasantly surprised. 

And, please, keep us posted.
