Fun posing/flexing at 135 lbs bodyweight

i was bored when i made this video....since i just got home from school. I know i suck at posing, so please dont hate....

anyways, im 5-4 and 135 lbs. right now, i want to bulk up to 150 lbs cuz im kinda skinny. I eat 6-7 times a day and still hard for me to gain weights.
Any tips or help would be nice, thanks, have a great day :)
