Good work.
I bet a Mars Bar that it was difficult to make that first step?
It is a marvelous, huge leap and very good beginning step.

Comments on the image as it is displayed:
It is probably a bit too compressed for that Camera Viewpoint.
At Full Profile those Handle Bars are very dominate, releasing the Shutter a second earlier, when he was at about 3/4 Profile would be nicer, I think.
Even so, the Lens seems slightly too long and probably you were a tad too far away - that's life - maybe you were shooting from the other side of the road - probably were as you're in the USA and you folk drive on the RH side of the road.
What's the full frame image look like? (What I mean the whole frame 'as shot' without any cropping?) maybe an even better crop is possible if the shot is wide enough.
I agree that Manfred's tighter crop is better, but arguably it would be better still if ti were a wider shot but slightly shot a little closer and cropped differently. (easy to say now, but the point in stating it is: your camera is so good, technically, that the maxim "shoot wide - crop in post" is a good one to remember.
The B&W conversion lacks a full range of Grey Tones - Manfred's edit has adequately widened that range of Grey Tones.

But,
moving aside from C&C of THIS PARTICULAR SHOT: The procedure of the shot was not the best suited to the reasons that I encouraged you to try your hand at street work (i.e. I encouraged street work for you to get better, quicker more confident at candid portraiture shot in situ).
This was an opportunity ‘snipe shot’; it is a nice shot, with strong lines and tightly focused composition and good strong elements. But as street work for your "practice" for your Candid Portraiture Work,
I suggest that you'll need to get closer; attain and gain rapport; and extract the Subject's Personality using that PROXIMITY - (i.e the perspective created by the camera and lens VIEWPOINT) - AND also use composition of the interesting elements to enhance that.
In this shot, you've stood off and 'viewed' the interesting elements of a scene and then recorded them for us to see, 'from afar', that
procedure is not usually the most conducive to creating excellent ‘Candid Portraiture In Situ’. So the message is, the procedure of ‘Practice and Training’ is just as important as the product the practice and training produces.
Yes, I know, that suggestion requires a few more steps which are further outside your comfort zone, but I am extremely confident that you can achieve that.
