Congrats, looking at your snake list, I notice you only have BP listed, is this your only other species to have worked with? The difference between a BP and a retic is night and day, so make sure you are ready for what's ahead.
Just a slight notice of concern - the dot / spots on your snake looks like it could be mites. When I got my white phase back in 2012 from Bob, it came with a nice case of mites, but it's easily fixed with proper QT and mite procedures, I'd be on the watch out!
There is a lot to cover in regards of what to expect with a retic, but at this point I don't know what your background with snakes is enough to give you more information to go with. If you run into particular questions, let me know.
Cheers
