Congrats on landing your first jump in the park.
Videos used for coaching like Snowboard Addiction's can help you with nuances that will make your progression much more rapid and help you learn the correct way so you look stylish. Remember the coolest spins and jumps are those that look effortless versus those that look like they are being muscled around.
Also listen up to the good folks on here that have a lot of knowledge.
Lastly, since you are new to the park, don't forget the proper park etiquette regardless of the lack that other may have...set an example for others.
