When painted to scale paint job it is pretty. Just in general, folks really like the PS2 builder kits.
But yeah, it's 4FNC. Frankly, a *lot* of extremely popular rockets are just 3FNC or 4FNC, and are either popular because of their paint job (e.g. Red Max) or... other reasons. As soon as I find out what they are I'll let you know.
Try making the scale bolt, rivet, and panel line detail . . . Remember, this is a Scale model, not something to slap together, paint any old color scheme, and fly !
