Very Simple 3D model Modification for Unity project

Hi, I purchased a swallow 3d model has animation from Unity asset store. [login to view URL] All animation for fly, idle, walk, land, taking off, etc looks great. The only thing I want to modify is swallow's tail and swallow body texture. I would like a little modification to the swallow's tail. If you watch the BBC video of British Swallows returning home you will see that the tail is forked and not squared off. [login to view URL] Can you make the tail like the video and deepen the blue as body is too light blue. Please check attached img. I think this will take a few hours work for export. If you can do this task perfectly, please apply. If you do this task well, I will give u more tasks. Please reply with "Swallow" so that I can know you checked full specs and attached file. Otherwise will be ignored. Regards.
