Thats pretty much right except the "lch" sound is also at the beginning two L's too (although Im guessing you just forgot to put that in), but to some people that might look like ch as in chips see what you mean tho! It's really hard to describe without having heard it, that description I pulled from some website isn't the best, but I thought it gave the jist of it
Don't worry Gabe, I've been trying to teach all the English people in my uni (which is in Wales btw) how to say double L and other Welsh letters/places/words (etc) and they always get it wrong too!
