3x3 Help

[ANormalCuber]

Hi! So I started speedcubing about 3 months ago and managed to get to sub 30 within the first two months. I really want to get to sub 20 . I average about 23-26s now. I found similar threads on the forum but they don't seem to be much help to me since I have a different case. I know full PLL and about 15 OLL algs. I do the cross in about 2( if easy)-4(if quite complicated) seconds. I do F2L(intuitive) in about 14-16 seconds. I do PLL in about 2-3 seconds and OLL in about 3-5 seconds. I feel that my F2L is a bit slow and need some improvement. I have been practicing lookahead for a while now and has dropped my times from 29-31s to 23-26s. Does anyone have any advice to make me reach sub 20? And am I improving at a normal rate because i seem quite slow at improving and is quite scaring me. Thx in advance.
P.S Sorry if i misspelled some words or have wrong grammar. English isn't my first language.
