Feedback request for my personal branding design

Hi, I'm trying to have a consistent design across all my services which include:

• blog articles cover images,
• Twitter images,
• slides etc.

I have added my blog URL + my avatar to build a personal brand.

I have added similar colours everywhere + I try to find some nice accent colour as I mainly use grays/grey-blue, same fonts.

I have created a consistent cover for all articles but I think there is a weak point. I'm a bit afraid that when all my covers will similar to this then viewers will ignore it on the timeline as not everyone will read the header.

Just look at the screenshot:

I'm a developer - not a designer so please give me some constructive feedback for a newbie :)
