'The Tree'

Making some good progress with 3ds the past couple of weeks, I have recently finished the 2 week Tree Project for Game Production, i have learnt new skills in modelling, unwrapping, texturing and using alphas adding detail where needed. I'm not quite happy with the final outcome as i could not get rid of these white fussy lines around my alphas, and apparently no one else knows the solution to this. I will probably start the project again in my own time and see if i can get round this problem by modelling another way. 

The tree may look like it's a winter Christmas tree with snow on the edges, but unfortunately its not meant to! I will find away around this error of mine! Also i would like to find another tree with some interesting features and maybe in a different setting or season so the colour and lighting effects will vary. I have enjoyed this project and have now found myself looking at various tree's when playing COD!
