In addition to the good points above, I'd offer a couple of very general comments, both related to thinking about the buyer of your images.

The big one is keywords. I think both Shutterstock and Adobe Stock are showing me your actual keywords (but it's possible they're suggesting topics, in which case ignore my comments!!). Be specific about places and details of your image, but do not put multiple locations, multiple seasons, all possible food ingredients for all meals. This type of keyword stuffing means the images will show up in searches where they're not relevant - it won't help your sales and may even hurt them as they get passed over a lot.

Some of your images are rather dull and flat and others have super-saturated colors (not in a good way). Buyers need to be able to use your images in designs & on web sites and most won't want to spend ages processing the images they license - especially if there are many other images of that subject to choose from. Try to get the look of your images more ready-to-use, if that makes sense. Here is an example of an image that is very flat and a second that is over-saturated, which might help explain my point a bit:

And you'll need to grow your portfolio a lot to see consistent sales. Try to find scenes or places you have access to - or some hobby or other interest of yours - that perhaps isn't already covered to death in the (very large) existing agency collections.

Good luck!

Hi lyudmill.
Nobody seems to react so I'll give you some of my thoughts. Remember, you asked for criticism and it's my personal view and it doesn't mean everybody will have the same opinion about it.

All were taken from your Adobe account.

The picture is nice but the part that is not focussed does catch the eye immediately and makes up a big portion of the frame. Use stacked photo's or compose differently that the part that is not focussed will attract less.

Again, nice setting. But the sky is washed out completely. The point to the photo is the mist on the water and the dark trees behind them. I would have composed it in a way the sky was not visible. Also there is movement on the water (the rings) that distract your eyes from the intention of the photo. Clear them in post processing or wait for the water to be calm.

The top of the trees are cut off (also on the bottom). Compose a bit better larger that you have the tops visible and still some room around them.

Your foreground is to much present but not interesting. If you would have moved to the left and just capture the rock, water and trees, it would have been much better.

If you see something like this. Go out of the appartment and take the shot behind the lightpoles. Now they are distracting.

Remove physically the two items that are in your shot and that ruin your composition. Or remove them in post.

Leave more space to the left. Your subject is almost out of the picture.

The photo lacks contrast. Food should pop out and be colourful. The photo is a bit flat and seems to be overlit.

And then generally speaking, pay attention to light. Best time is during sunset/sunrise. I know it's not always possible but your photo's (especially landscape photo's) will improve by a factor thousand. Pay attention to breathing space and make sure your composition is balanced.

Good luck and I'm sure you will improve and hopefully get better sales.

ps: If you are interested in landscape photography I learned a lot of these two guys (and there are many more):
