Congratulations on your trifle! I had to look it up - I never have had one, or even seen one for that matter. Most of the photos on Bing looked not good, but yours sounds nice: raspberries, custard, pound cake, whipped cream, compote. I like all of those things. Really sorry about the frozen berries - fresh raspberries are one of our favorite things here.
Dumb question, but without going back hundreds of pages and trying to find it (I just clued in to the fact that you are taking a class) - are you going for a chef certification of some sort? My Second would like to be a special-diets chef, considering that she is a dairy-allergic celiac growing up alongside a sister who is on the SCD, so she lives and breathes alternative food. I worry about her a little bit, though, my Second and her choice of occupation, because she is a MEAN and STINGY little cook. She thinks that she should be in the kitchen all by herself the whole time she is cooking something up in there, and nobody but nobody (including the Lord Himself) ain't allowed to come and sample and pick.
I keep telling her that if the hordes come running, that is a POSITIVE thing and she should just account for that and make more food so she still has enough for dinner if everybody here wants to sample. If her food were crap, everybody would be making sandwiches and stuff so they would be full before she dished up, you know?
