Not in particular order:

It's hard to choose based from the overall appearance alone,
so I used these criteria:

• [50%] Overall Aesthetics (Colors, Toppings Arrangement and Form)
• [25%] Resemblance to "Bitcoin Pizza Day" and/or "Bitcoin" theme. (e.g.: Plain Pizza with a giant "BTC" = 20pts)
• [24%] Estimated effort to match the Theme. (e.g.: Plain Pizza with a giant "BTC" topping = 4pts)
• [01%] Presumed taste.
