thanks mates for the response
ok here goes, shall start from the beginning:
first took a cheesboard(hardwood) and cut all the way trough a halfcircle out of it and siliconed - screwed a thinner piece on the underside so you make a halfcircle basin in your board ( take care the basin is watertight ) next step when you finished making your bank ( sloping : land-water) is to maske off the place were your piece of armour is suppose to come, i've just used a piece of cardboard and painterstape for that. next i've brushed the hole area were the ice is with a mix of 50/50 white gleu/ water (about 3 coates) to seal eveything, now paint the bottom of yous river or stream with dark green-brown (just play around abit with colours
) and lighten it up to the bank,used enamels for that. the ice is just paraffin wax heated so it flows like water (thats why everything must be watertight
).when that hardens just remove your masking and clean it up a bit were your tank sits. now take a thick needle and scrape some cracks in your parrafin to simulate the strain the ice is under of the weight of your tank. now i'll brushed one layer on the ice with gloss gel medium from LIGUITEX so you get a oneven apperence of ice. when that's all dry gleu your tank to the base and poor in thin layers clear polyester resin around , on the 3 layer put some flat broken pieces of parrafin in your resin so it float in between layers . on the last coat of resin just play with it a bit with a toothpick to get some ripples
.almost done, now when dry i've brushed several layer on the resin with gloss medium ( just let it dry between layers but if you wand some white wavetops build it up thicker, it's stays white then).
and the snow is just your basic groundwork with broken leaves then brushed a thick layer with a mix of baking soda-white gleu-water and when dry sprayed a mist with white gleu and water and fine sprinkled from above a light coat of pure baking soda.
well i'll hope it will help somebody to take a leap in making suth thing , it was a pleasure for me to make it , ohhhh Sorry for my english
