From the freelance side of things, I have found a lot of photographers and artists in this community tend to use the same style of formatting for their marketing collateral; usually bright and colorful pastels, loud colors, large curly fonts, etc.  Sometimes they don't even do that and instead just use designs that are bare-bones basic.  The issue for me is that a lot of the time it all tends to bleed together and makes it harder for the individuals to stand out.

To stand apart from the crowd, I take a bit of a different approach by branding my content with a Fall/Halloween theme, using a skull as my primary logo, colors usually associated with Halloween, and also keeping somewhat close to the community by using an 8-bit style skull and text for the core logo, similar to that of the era of games the community has grown up on.  Simply put, it's a design and color scheme that is hardly used and I find helps to ensure my brand is a bit more memorable.  Also, spooky Halloween content is fun!

Again, playing to the strength of Instagram, I have created multiple graphics used for Instagram stories that can be saved on my profile.  This way, when visiting my page, any important freelance information is readily available.
