Fantomatik Orchestra opening animation

Hi everybody in this great forum

I’m trying to realize a small animation with Blender for an italian street orchestra called Fantomatic Orchestra. Their simbol is a strange yellow creature and they’d like a small animation in the opening of their web site where this creature comes in walking and playing the trumpetm, then stops in the middle of the field and the logo of the band comes out of the trumpet.
The mesh model comes from luxology Modo, but “materials” and all the other things for final animation will be realized with blender.
I’m new with this software so every help and comment and critique will be very appreciated!
Thank you so much in advance!
