I want to go eat now as well. Some good attempts for your first go, I like the way you have included the chopsticks and the photos have ended up clean and neat. Just be careful on keeping the horizon straight on the champagne glasses.
Personally I'm a person who likes a clean background.
I feel that the, whats that? Teapot? Saucepot is rather distracting with it being chopped off. If you want it in your picture either have the entire pot in view or remove it.
The green on ur veggies look more dead than vibrant... Did you cook it for a pretty long time?
Also take note of the placemat... I think it must have been a bit on the small side because it tapers off into another background which is also another distracting element..
I'm not sure about you but I would straighten the placemat abit so that the grains.... sticks? meh...
faces straight in one direction instead of diagonally.
A good comparison would be your gyoza to your fried chicken.
It looks alright to me.
However; take note. make sure all surfaces are dry. The water smudges on the table is distracting.
But overall a good try for a first timer.
