step:
Think about the structure before doing it. Create a new layer and fill it with black. Create another layer, select the top with the Rectangular Marquee Tool, and fill it with green. As shown in the picture:
Create a new layer, use the polygon tool to cut out a suitable place, and fill it with red. Then press CTRL+J to copy the same layer and move it to the appropriate place, as shown in the figure:
Create a new layer, use the polygon tool, select a place you think is suitable for the snow, select it and feather it to look more natural, then use Filter-Blur-Gaussian Blur 5, as shown in the picture:
In order to make this piece of snow look more three-dimensional, open the layer style-select Bevel and Emboss, adjust the parameters to your liking, and then open Filter-Distort-Ripple. The effect is as follows:
Next, make the Christmas tree. Also use the polygon tool to draw a Christmas tree look. As shown in the picture:
Then fill it with green, create a new layer, and make the outside of the tree look like it is covered with snow. The method is the same as the snow field in the previous step. As shown in the picture:
In order to make the Christmas tree look more three-dimensional, you can also use the bevel and embossing layer style. I didn't adjust it in this step, but you can adjust it at the end. Color the foreground red and use a brush to paint at the appropriate location on the tree, as shown in the picture:
Then drag the puppy and hat from the material into the picture, as shown in the picture:
Then put the picture of the candy in the material in the appropriate place according to your favorite way. It depends on how you like it. I put it as follows:
Next, make a stationery to write congratulatory messages on. Use the Rounded Rectangle Tool to draw on the right side, as shown below:
Then right-click to create a selection, and then delete the current layer. After deleting the current layer, the selection is still there. Then press Edit-Stroke, and I traced 5 plain white edges. As shown in the picture:
Use the same method to draw a smaller one inside the rounded rectangle. Then fill it with white. Then fill the middle position between the two rounded rectangles with red. As shown in the picture:
To make it look more three-dimensional, go to the Bevel and Emboss layer style and select Drop Shadow as well. Move it again. As shown in the picture:
The red edge of the letter paper looks a bit monotonous. Create a new layer and use the polygon tool to select a suitable place, and then fill it with green. As shown in the picture:
Then pull up the bell of the material. As shown in the picture:
Finally, color the foreground to white, combine it with the brush tool, and then combine the opacity and brush size to paint the look of snow. Then make appropriate additions and adjustments to the details. As shown in the picture:
Finally, write blessings on the letter paper and that's it. Haha, as shown below:
