I Just started learning how to model a face, this is one of my first projects. Is there anything you would do to make the topology better?
It looks like that part needs to be fixed. It’s also important to keep 4 vertex, but if the edge flow is bad, it doesn’t make sense.
Is it supposed to be a ball-shaped face? Do you have some reference image that you’re working from, or is it all from your imagination? Because it’s not a good idea to work without a reference, especially if you’re new to this.
best way is to place the image under the model and “trace” your mesh over it. Like this:
If you’d like to see a masterclass in modeling a face from a simple cube:

In regards to face topology, here’s some examples:

Blender has a free, downloadable asset bundle that has heads with proper topology that you can learn from:
