I feel you had the potential to get a lot more out of this year, but you've come back and posted your progress, and there has been some progress. That's an infinitismal improvement over the vast majority of human beings, and probably sets you ahead of a lot of the people who did enter at the start of the year, never to be seen or heard from again.
4kg in a year may not be ideal as a beginner, but do that again next year, and the year after, and the year after that....and you'll be going places with your strength and fitness.
