Here is an example of my graphics design skills in putting together a fairly basic promotional banner. This banner is formatted to be used in a blog post on a website, as the lead image for social postings, and as part of an email newsletter campaign.

As with all image work, it's important to keep PSDs (Photoshop) documentation to support future iterations and compatibility needs. I've used various asset library services for this purpose, such as Bloomerang, Confluence, and others both for nonprofit and for-profit organizations.
