Thanks Greg. It really is just technique much more than talent. You said it was snowing, so you took the photo inside with a flash I assume? I will only take my photos outside, in natural light, on a bright but overcast day. Chas does it the same way, as does Roy and R1 and others. Next day it is like this, try taking a few more photos of your helmet to experiment. There is a thread on this HERE worth a read, I no longer take mine on a pole, but as I explained above.
Some like helmets on black like you have done, I prefer on a grey sheet of artist board curved up against the house, so there is no edge visible. But the daylight defused by cloud in my opinion, makes a huge difference.
