Let's take as a basis here such illustration of a fir-tree in snow that it was more clear to you how to draw.
So, very thin lines we will outline the main form of a fir-tree in the form of a triangle, then we will represent its branches from both parties.
We start representing from top to down, you can on the contrary as it is convenient to you, snow cover, but not completely, only partially.
Now erase part of a contour and dorisovyvay more relief forms of snow on fir-tree branches. Then we start darkening sites which remained green, are without snow.
It is more convenient to me to do it from top of a fir-tree and to go down, thus it is possible to add new elements, i.e. fir-tree branches in snow.
Add still shadows or more dark green color if you use colored pencils, paints, in places of deeper, i.e. for example, under the bases of branches, from below branches.
Snow at us not purely white and smooth therefore by very light shtrishka we do shadows and friability of snow. For more picturesque look it is possible to make a background, you can make any other what is pleasant to you. Fir-tree drawing in snow is ready.
There are lessons:
1. New Year tree
2. Simply fir-tree
3. A fir-tree in snow a water color
