Honestly not feeling the panning too much, feels too heavy on the right. It makes me think of sonic lol. Oh... I just looked at the title and tags, well you did very well and faithful to the original then.
I feel like you could do with some reverb to help fill it up a little more and make it feel a bit dreamy as well, a little flanging or phasing would go a long way too. You could increase the release and add vibrato to the synth for something similar if you don't want to use effects.
