quick Houston trip by myself, need some tips!

Hello, I(F) will be traveling to Houston in a couple weeks for a concert, so I'm wondering if I should have some cautions while being in downtown?

My hotel will be close to House of Blues so I plan to walk back to the hotel but I don't know how safe downtown is at night, are homeless dangerous? how safe are downtown streets at night? Tips on safety or comments about the city would be greatly appreciated!
