I'm with the others here. I think you did real good for a starter kit. I started out with mostly all Craftsman.
I've been hustling my game for 2+ years now and have almost all Snap On (Early mornings to the sales, late night on eBay, LOTS of de-rusting stuff, etc). Not necessary, but hey, what the hell huh.
Some of the things I would say to maybe think about focusing on next would be, and this is just a suggestion, and I think cost effective at that.
Williams Phillips screwdrivers (IMO Cman phillips are junk after using high quality ones)
Sunex impact sockets in 3/8 drive with a Milwaukee or DeWalt or ??? battery 3/8 impact.
Snap On needle nose pliers (good condition ebay maybe...)
Other than that, I think you are set for doing a lot of DIY work! Now the fun begins.
EDIT: spend a little money on organizing stuff. Whether that be socket racks or trays, wrench holders, etc. It will make life much easier and cause a proud feeling when you open your tool box to work on something. No one said this can't be fun. lol
