This is my step of working on the e-wallpaper as my assignment 1 for computer graphics.

First,i open the file and go to the new image(Ctrl+N).For this e-wallpaper,i was used A4 size and 72ppi.Next,i click on new layer and fill it with black colour(New layer>edit>fill>fill with black color).

Secondly,i used the images that shown above and move on the top of it to the work space that have been filled with black.I used layer mask to remove unwanted things on this photo.

Next,i used quick selection tool,to select part of the image that i want and place it nicely on the workspace.

Next,i repeat the step above on this image.I used another image to place on the workspace and place it nicely,to move the picture around you just need to press (Ctrl+T) either  to move the picture or to resize it.Next,i used layer mask to remove the unwanted things on the images that i've been placed.

After that,i used another image to place on the workspace and place it nicely,to move the picture around you just need to press (Ctrl+T) either  to move the picture or to resize it.Next,i used layer mask to remove the unwanted things on the images that i've been placed.

After that,i used the text tool(T) to make the tittle of my wallpaper,i type on LOY KRATONG FESTIVAL and A FESTIVAL NOT TO BE MISSED.Next,i merge down the two text and i go to blending option to change the colour and put some gradient on the tittle.

I've used brush to  make these flower and combine it to the text.

Lastly,i've used curve to adjust the colour of my wallpaper,and give the nice color balance on your photo.
