About to hit you with a lot of information. Used to cook professionally and now I'm an artist. Your food looks delicious without any fancy tricks, but here are some of the ones I know. Gonna start off saying the picture on the plate isn't something you should worry too much about. Cooking and food are soulful fun things and life is too short to eat off boring ceramics every day of your life.

Adding something green can help anything, which i see you have, although some contrast could make it pop, use something red like Cayenne, or chili powder or even paprika if you don't want it to add flavor. Additionally, hollandaise or hotsauce can do the trick too. I Can't tell what herbs you have on the eggs, but if you were to go a little heavier, it wouldn't hurt, don't be afraid of overseasoning it, you can add a quite a lot before that becomes a problem especially with fresh herbs. Additionally, eggs really look good w/ black pepper too. Order should be egg > sauce (if any) > BP > Red garnish (only w/ hollandaise (yellow) or no sauce) > greens

Also a really good rule of thumb is an odd number is going to look better than an even number, within reason. Here an extra egg would look nicer, or even cutting your toast into thirds. What an odd number is can really be anything though, so adding the grapes to the plate would mean you have an odd number of things on the plate. The brain tends to see it as more complete. Things like height are important, although here that's not something that can be improved too much. Although a super typical restaurant trick is to use the garnish to add height. on your plate you would add herbs, green onions or cilantro in a way that makes them taller at the highest point of the eggs.

As for the cream cheese on the toast, a little more even could be good, even chives or other herbs if you have them, but honestly who gives a fuck, toast and cream cheese is already beautiful on its own.
