Adrie,
very nice composition, sharpness and color.
Mark Stodter

Good composition due to well accomplished use or rule of thirds;) Horizon and windmill are exactly in the right places, windmill is turned towards the center of the image and the largest tree balances it nicely. Nice colours also and delicate (not hard) light enhences the peaceful winter scenery. I like also that in the sky there is some "life" and it isn´t monotonous "dead blue". I believe you can use the same scenery again and shoot it in different seasons in mist, storm, pouring rain, dusk, at nightfall, snowstorm etc... Your E-1 will handle all elements except possibly meteors.
