definitely a great start you've got going here. One big think I would suggest is playing more creatively with your stereo field. This is something I have really been working on lately. Making something "big" is just as much about width as it is about volume.

I usually like to pick one main element to make as big as possible. Sometimes my lead (in this case it would be tough since your's is intentionally very thin) so I would fatten up those pads. I read somewhere you want to try and aim for your high end being 100%wide, mid highs 66%, mids at 33%, and bass dead center.

Hope this helps
