Not bad.
Boycott is spot on, I've made this point 2 or 3 times on this forum before. Batsmen need to perfect a technique, and that means working on the forward and back defence. Once you've developed this technique, you can adapt your game to ALL forms of cricket (T20, etc). You can't do it the other way around, and sadly many younger players now are working more on the T20 game, which pretty much rules them out of Test cricket.
