Welcome to NGA, @Jaco17
Congratulations on your very successful first attempt at growing a pumpkin in S. Florida, that's a beauty!
First Prize is one of the "giant" pumpkins, apparently potentially growing to 300 pounds. When did you actually plant your seeds (or the plant, if that's what you started with)? Pumpkins usually take around 120 days from seed, and if yours was "pollinated on 2/21" (I'm assuming you mean that before that there was no baby pumpkin growing?) I don't think you have a mature pumpkin there. If you harvest a pumpkin early the flesh will be very watery. From your photos it also appears to be a lighter yellow than the mature orange color that it should have. I'd let it keep growing at least until you hit the 4-months from planting mark (if you haven't already) and see how it looks then.
Also, there's a lot of difference in how well pumpkin varieties work for making pies (some have nice smooth flesh, some are pretty stringy), so if, once you harvest your big pumpkin, you are disappointed in it as a pie pumpkin, don't give up -- many of the smaller types make great pumpkin pie (as do many winter squash).
