PHOTOSHOP PRACTICE: CELL PHONE

It was a homework about practicing using the software again. I think those days we had too much project to do and I didn't sleep well, so I didn't pay much attention to do this work. I drew the cell phone that I am using now, but I drew it too small.
It will be another homework of computer drawing two weeks later, I am really tired of doing these works but I hope I will pay more attention of it.
