Hi, I need some help in snow effect in photoshop

[jheign02]

I am making more like fantasy map and I want the land to put some snow..not totally covered with snow just small amount of snow here and there.. Does anyone know how to achieve this? Can you help me guys? Thank you so much for your help...

I would place my snow layer as a repeating image of snow on top of whatever is my existing layer of land texture, then apply a fractal cloud transparency onto the snow to allow the texture beneath to show through. Depending on how much snow I require, I'd vary the scale and difference between what shows through and what does not until achieving the desired result. Of course not knowing what style of map, its difficult to suggest more than that.
