I think everything on your portfolio is absolutely beautiful beside your own branding.. kinda odd I know but us designers are our own worst critics.
When I saw your branding I was prepared to not like your portfolio and was expecting the worst.. then I was blown away by the quality but surprised by how your branding looks like it was made either by someone else or years ago when you didn't know anything. I think its time for a rebrand.. make something that shows off the talent which you clearly have.
