As a i don't have Photoshop software and have another software that is to beautify photos without too much professional knowledge. So for the first four photos, i make use of the advantages of the software to merge separate photos together, and rotate some pictures of myself as when  the picture are taken at vertical direction. I also adjust the size of picture and make some adjustments in terms of brightness,hue,color balance and so one.
The last picture is edited by a online photo editor(http://pixlr.com/editor/), compared with Adobe Photoshop, it has less function but it can save the storage of your PC. I try to use this to edit some of my photos, but limitation of less function make me difficult to achieve my plans. So i only adjust the brightness of the picture, make three layers to edit the blue butterfly, the other butterfly is originated from the first one, i freely transform it and make some distortion.
Then i use some brush to draw some stars with different shapes and colors. Using online photo editor is also not that stable as during your process of editing, it may stops and all your work done before is in vain. I'll edit other photos later and use reliable software.
