Buddy, you're only 16 and making some fantastic videos. Kudos to you!
I'm not a wedding shooter, more commercials / film and I own a production company. I just got married I'm currently editing 2 of my favourite DOP's footage of our big day, so this post caught my eye. ( I cut my teeth shooting events for brands all over the world)
I'm not going to give you much advice, I just registered to say - keep up the good work! My general advice :
You have a great eye and any questions you have, will ultimately be answered through shooting/editing hours, watching what other producers are doing (bad and good), sometimes finding yourself in a shitty situation and learn from it (and laugh about it later), Don't be afraid to ask someone to do something again - you're the professional and they'll take your advice to get the best out of your service (as long as it doesn't disrupt the flow of the day), be aware of products that will better your trade, but don't get too obsessed with gear and buzz words (4k wedding video!(unless they'll pay for it)), it's not the tools but how you use them!
But dude, you're on the right track and you look super talented. PS Don't ever, ever let any negative comments/feedback get you down, If it's client side, they usually have no idea what is involved in film/editing, if someone in the industry is barking on your comments, they are probably somewhat insecure/jealous/generally sad.
Also, in my conclusion ; "dude you're doing awesome" ..... Keep up with all genres of music, your brain will be a music library, MOST importantly - when you feel like taking a break from every day filming, take a break, film new Projects, projects that are different from your day to day earnings, it keeps the mind fresh!
In conclusion...bridesmaids dig creative folks- get in there bro! Ha!
Hope this helps !
