This is a neat concept I doodled up at work. I've seen similar before, but I drew this freehand myself, then scanned it in, inked, shaded and coloured it in Photshop.

Time spent: 6 hours total for all the colouring and inking.

It is of Winter and Munich's tails entwined with love for V-day.

I also uploaded the lineart as a freebie since I like the lines a lot but don't have time to colour any more for commissions. They are located at:

Enjoy, and please let me know if you use my lines!
