I suspect you will come to LOVE Nik! I use silver efex all the time, color efex occasionally. I don't know what I'd do without Silver! I like what you've done here -- very soft tones contrasting with the frigid feel of winter.
Lovely shot as Taffy above says the Nik collection is great particularly for B&W I also like the pro contrast filter in colour Efex worth a play when you get chance. Thanks for following my project as well :)
