lol my arms are just over 18 inches lean as anything, i can bench press 170kg, and one arm dumbell row 120kg each arm, and bartbell curl 65kgs, squat 260kg, deadlift 310kg, close grip bench i stopped doign after i hit 140kg started hurting my wrists so i replaced it with dips
i have weak arm genetics though so ur arms most likely be alot bigger if you had my lifts
as mentioned above dont worry about the babrlel curls and close grips
chinups and dips will build big arms, curling 35kgs will never giv you a bgi arm, but doing a chinup with 100kg behind it will, or doing dips with 4 plates added to a belt will build big triceps
