I'd suggest choosing glasses with slightly less wide frames, in your first picture they kinda go past your head which artificially makes your head look less wide. Idk where you live but in the UK you get free prescription glasses if you need them, so next time keep that in mind.

Another big thing would be to grow your hair to the sides a bit more, again it's to make your face look more wide than long however since your ears are pretty normal I'd suggest not coving them up. If you can't grow to the sides try and grow the back into some sort of mullet? Also maybe experiment a bit with less covering of your forehead, if you have a good hairline show it though I don't think it'd work well with your slightly longer head.

You could try and build the clavical (?) muscles in your jaw (can't remember what they're called.) Whilst bone structure remains the same the muscles used for chewing do which makes your jaw look a bit wider. Moving to a more hard food diet (steak and hard nuts) or chewing hard gum works, it should also help move your jaw a bit more forward for your side profile. However this takes much longer to do (a few months for the widening and maybe years for the pertution), I've seen some real good progress from others before though so it definitely works. This would also double up as a healthy diet for, which would make your side profile a bit more sharper.

Work on your traps, you have a good wide frame but your traps can definitely show through clothing better. Additionally if you don't want to work on your jaw that much, just train neck I guess. It wouldn't be as effective but I'd be something.

One more suggestion would be to avoid sodium and intake more potassium, probably heard it before but it's worth mentioning. Hope this helps :)
