I'd say Jmac's execution was a little better, but here's my feedback on both
Elow has too much high end in his master, some sounds could use some Freq cutting, or some panning so everything can have its own position in the stereo field with some leveling to keep everything within the same DB range. Jmac's was good, but its the same issue: Frequency cutting, though not as bad. I'd suggest removing some mids, n boost the highs just a tad a bit to make the bass shine a bit more.
The highs on elow's dont need too much cutting, just a tad bit. It would also be nice if some of the FX could move around the field just for ear candy, but not everything. Just certain sounds in certain positions just to make it feel more wide. Nothing too crazy, hardpanning would be a bit much.
