Fantastic, well done. Periwinkle is a bloody nightmare, we really struggled with it in our last house. As for the bramble......!
You're right putting in the hard work now, and getting things sown early. It's a mistake I make every year, and swear I won't again. Annually. The weather here in Central Scotland is very temperate, I did a huge amount in the garden today, and am feeling the optimism of Spring. Bring it on!
