I have done quite a lot of 3d modelling in blender mainly for games that were later made in unity and have also created the animations for those games. I was thinking of a generic snowman with the sun glasses, snowboard and scarf as separate models, just let me know if you want it all in one file. I'm not to sure on the size you want but if you choose me, when I send you the file, just let me know if its too big or small, and I'll adjust it, also when you said "jump with rotation 360 degree's" did you mean a flip or literally a turn? If there are any other details i haven't mentioned feel free to let me know. I hope you Choose me and if so I look forward to working with you.
