The most obvious difference is the wings. In the first game, the wing membrane was a completely opaque texture, covering the whole polygons, while in Spyro 2, the lower edge is transparent to make it look more realistic.
The color of Spyro's cheek is slightly different too, being more blue-ish on the Spyro 1 model.
I noticed this two days ago when playing in Fracture Hills.
