A Picture. A Big Question. A Boy ... I Guess

I look a picture on my screen for a long time

I realize that there is a question in it.

There is a boy looking the question amazingly.

A lamp is shining.

And I guess -> A Ghost ???!

- correct my mistakes, please ! Thank a lot.

hmm...

At first, we use "look" with the preposition "at" or some else, but in this case, we use "look at", "look at a picture..."

The second, this is a report post, then, you should use the past tense
~~> I realized that....


Finally, I dont see any picture here... upload it somewhere then post it, so ev'rybody can view it (Just my suggestion )
