Portfolio problems

Hola, hello, ciao, oi.

i did the portfolio project, and everything went well. (checked)

now, im revisiting the first project, to do a make over, and have little problems with it: but, my big issue is that when i updated the picture of the new project1 in my old portfolio project, i couldnt put it in his place (centered); but only in the cell phone mode, in the computer looks well.

here is my portfolio in CodePen link

Gracias, thanks, grazie, obrigado \o/
