Do you want to be able to add to your portfolio creative sketches/ collages ?

These are very liked and even just adding one makes your whole portfolio look more creative. You can do these by hand or in Photoshop ( much quicker). 

They are very easy to make once you learn how and get used to the technique.

I would usually start witch choosing a topic (dance), find a few images that go well together - use similar colour, style, lightning. Do you research - images need to match. 

Then to create a white outline of the object go to Photoshop -Image- Threshold. The rest is simply drawing using different size brushes. Also don’t be afraid of leaving white space around. The image doesn’t need to be full colour. When you leave white areas, it makes your work more abstract and creative.
