This image invites us to a deep reflection about currthe present...

(1) It should be "invites" not "invite", since "[t]his image" is singular.
(2) "Current" is an adjective. "The present" is the noun.

This image invites us to a deep reflection about current society.

Again, "[t]his image" is singular.

We can see a crowd engrossed in their smartphones, with their eyes fixed into the bright screens that buriedy them in a virtual world.

(1) "a crowd in their smartphones" implies a crowd physically inside their smartphones, which is obviously not what you meant.
(2) "in" is the wrong preposition to use here. You should use "to" or "on".

They looks like immersed inthey inhabit a cold earth, the weather suggesting a disconnection with the reality that is around them.

(1) It should be "look" not "looks", since "they" is plural.
(2) immerse: involve oneself deeply in a particular activity. "immersed" doesn't strike me as very appropriate in this context. Allow me to suggest "inhabit".
(3) It's a subtle difference, but "disconnection" and "disconnect" are different. "Disconnection" refers to the state of being disconnected, or the act of disconnecting something. On the other hand, "disconnect" refers to the actual discrepancy or lack of connection.

In contrast, ion the surface we can see an a lone character pushing a lawn mower over something that looks like a field of buried heads field, with only their faces revealed.

(1) You can't ever be "in" the surface; you can only stand "on" it.
(2) lone: having no companions; solitary or single.
(3) "buried heads field" is understandable, but "field of buried heads" is much more natural.

(I don't know how I can i punsert an image in the post, so, here is the link: ( https://i.ibb.co/ksXTrXGq/495935971-1039220718273691-8809786197781849979-n.jpg )

(1) "Can I" is used in questions ("Can I insert an image?"), while "I can" is used in statements ("I don't know if I can insert an image."), though in very casual speech, both are considered acceptable, because people mix them up frequently enough.
(2) "put" is okay, but "insert" is more appropriate, or, as someone else has suggested "attach". By the way, you need to purchase Premium to insert images.
(3) The comma may be omitted.

Put also makes perfect sense, but attach sounds better.
