I'd look for any of the "how to get out of a slump" or "I'm burnt out on ______" posts on here
since you've built before, you're not a newbie, so going all the way back to the beginning is not really where you are,,,,,,sort of "coming back from a 5 year break" is more where you're at,,,,,,and looking at the Wildcat you posted,,,,you don't need newbie advice
so, do what they tell the "slump guys" to do,,,pick a subject from a mainstream company, from Monogram to Tamiya,,,,,,and dive back in,,,,,,,that way, if you do wind up needing advice, you'll be able to talk to lots of people that know the kit, and can give you some help
a couple of builds from now,,,,,,you'll be topping that Wildcat (if that's possible), and right back in the swing of things
