I need opinions and advice/tips!!

[HuskyMedia]

I'm 15 and I started working out back in November and I have noticed that my body is changing and I'm getting stronger, but I know eventually I will have to change/add my workout routine. I got a bench press with plates that equals up to 100lb, so I can work on my upper body, etc. I was hoping if someone can give me advice for where I should implement the bench press into my routine and if my gains are pretty good for a beginner. The attached images are from when I started on November 5th to December 24th.

Workout Routine:
Monday
2 sets of 35 regular curls on each arm, 45 dumbbell press on each arm, 15-20 push ups & 8 diamond push ups

I personally set each day for each muscle group so like Monday is my legs Tuesday is shoulders Wednesday is chest thursday is biceps and Friday is triceps for myself. I do a light workout till I’m generally jus getting a light sweat then I stretch for 15 miniuts and get to my routine. And afterwords I cool down stretch I’ve only been going three weeks my self send me a add and we can converse are advice if you like
