just checked the second one, it is a little warmer but not much really to be honest, it's a bit warmer in the low's but not overall, the mix sounds quite dry overall i thought and some of the levels are not in balance with each other, everything feel's kinda pushed to the limit and doesnt leave much headroom. Try putting the mastering thing out of your head, and concentrate on specifically processing the actual track parts/channels more, as really you want to get the sound as natural, balanced and full as you can before you try any mastering on it.

i really think the plastic sounding kicks should go, they take away the main rhythm somewhat and cut through really loud and thin, very top-mid and this leave's a strange feeling of space imo. The mix need's to gel together alot more still i thought, and maybe bring the master level down and work more power into the seperate elements, try cutting the bass on the kick to around 60 - 50 hz, or there abouts, fiddle around a little.

it's a good track, and a clean mixdown but clean doesnt always mean effective, full etc

it not crit so dont take it the wrong way, just trying to provide a more detailed view, not that im an expert or anything, just offering tips!
