I think you're right. That one ^^ has already had more views in the last hour, then the self portrait from yesterday and the beach before that combined! lol..
But by the same token, explore doesn't seem to like them. Well not mine anyway. My top 6 sorted by 'interesting'.. No 1, 3 and 4 are Lego. 2, 5, & 6 aren't and those 3 all made explore! lol.. One of them has even knocked my strawberries bouncing pic into 2nd place and that got to 5th in Explore*
*Yes, Explore is a massive popularity contest with no real bearing on how good your shots are. But I like it
