Great start! It is definitely recognizable as Mr.Bean. How far are you wanting to take the stylization? On a 0-100% scale 0 being realistic and 100 being extreme I would say you are as around 10-20%
The side view of the nose is nice it pulls out very far but from the front it feels natural almost less extreme than the reference photo. The ears don’t really feel exaggerated much as a normal ear goes from just below the nose to the top of the eye/eyebrow area and that is how they are sized in your sculpt currently.
Also the shape of the nostrils in the reference photo is an area you could exaggerate. The nostrils really go upwards to where the tip of the nose is a good bit lower than the sides of the nostrils. You could push that much further.
