Presenting work to clients is a hard enough task in itself. Taking some of the pressure off by using PSD mockups is a fantastic way to present work in a clean and professional manner, whilst the client gets to see the project in-situ.
You can download the mockups shown below for free. Use these to improve your work, your presentation and client satisfaction. Click the headings above the images to be taken to the download page.
I hope that you find some of the above mockups useful for your own designs. They are definitely an addition to any "resource" folder you may store on your pc!
